This document discusses refraction of waves, including light waves and water waves. It defines refraction as a change in direction of wave propagation when moving between two different media due to a change in speed. It describes how the wavelength, frequency, and speed of waves change when moving from deep to shallow water or vice versa. Specifically, it notes that wavelength decreases and speed decreases for waves moving from deep to shallow water.waves

1. Interference occurs when two waves meet while propagating along the same medium. This can result in constructive or destructive interference depending on whether the crests and troughs of the two waves coincide.
2. Young's experiment demonstrates interference using a double slit. An interference pattern of light and dark fringes is produced on a screen due to the superposition of light waves emerging from the two slits.
3. Young's formula describes the relationship between the interference pattern and the wavelength, distance between slits, and distance from the slits to the observation point. The distance between fringes is directly proportional to wavelength and distance from slits, and inversely proportional to the slit separation distance.1.2 reflection Fizik SPM

The document discusses damping and resonance in oscillating systems. It defines damping as the gradual decrease in amplitude of an oscillating system's oscillations over time until they stop. Damping is caused by the loss of the system's energy as heat. It decreases both the amplitude and energy of the system's oscillations but does not change its frequency. For oscillations to continue, an external force must be applied to supply energy. Resonance occurs when a system is driven to oscillate at its natural frequency, producing maximum amplitude oscillations. Examples of resonance effects in everyday life are also provided.1.5 Interference of Waves

1. Interference occurs when two waves meet and their displacements are combined according to the principle of superposition.
2. There are two types of interference: constructive and destructive. Constructive interference occurs when displacements are in the same direction, increasing amplitude. Destructive interference occurs when displacements are in opposite directions, decreasing or canceling amplitude.
3. Young's double-slit experiment demonstrates wave interference using a laser and double slit. It produces bright and dark fringes resulting from constructive and destructive interference of the light waves.2 sound sources wave interference

1. The document discusses interference and diffraction of waves, specifically light waves. Interference occurs when two waves meet and either constructively or destructively interfere. Constructive interference occurs when crest meets crest or trough meets trough, increasing amplitude. Destructive interference is when crest meets trough, canceling the waves' effects.
2. Conditions for interference include using monochromatic, coherent sources that are close together. Interference of light waves creates bright and dark bands called interference fringes. Reflection is when a wave bounces off a surface. The angle of incidence equals the angle of reflection. Reflection of light follows these laws.Wave interference learning objective

Wave interference occurs when two waves interact along the same medium. There are two types of interference: constructive and destructive. Constructive interference happens when wave displacements are in the same direction, while destructive interference occurs when they are in opposite directions. The type of interference can be determined by whether the path difference between waves is an integer or half-integer multiple of the wavelength.Interactions of waves
Interactions of wavesjmemler

Waves can interact in several ways when they overlap in space. Constructive interference occurs when wave amplitudes add, increasing the overall amplitude. Destructive interference happens when wave amplitudes subtract, decreasing the overall amplitude. Reflection is when a wave bounces off a surface, obeying the law of reflection. Refraction is when a wave changes speed and direction as it enters a new medium. Standing waves form from the interference of traveling waves reflecting back on themselves, creating nodes and antinodes. Resonance amplifies vibrations at an object's natural frequency.Notafizik f5c1

This document discusses the phenomenon of diffraction through a single slit. It defines diffraction as the bending and spreading of light waves around an obstacle. For diffraction to occur, the size of the slit or opening must be comparable to the wavelength of light. When monochromatic light passes through a narrow slit, the light rays are diffracted and spread out, forming a diffraction pattern on a screen. The pattern results from constructive and destructive interference between wavelets emitted from different points of the slit. Points of constructive interference appear bright, while points of half-wavelength path difference appear dark.Difraction
DifractionNurul Fadhilah

Diffraction is the spreading out of waves when they move through a gap or around an obstacle. It occurs when the size of the opening or obstacle is comparable to the wavelength of the wave. Some key points:
- Diffraction causes the direction and shape of waves to change while their wavelength, frequency, and speed remain the same.
- For water waves, diffraction is more obvious with a small slit versus a large slit, as the waves are more circular around a small slit.
- For light waves, diffraction patterns like bright and dark fringes can be observed using a pinhole or single slit, but the effect is less obvious due to light's small wavelength.
- Experiments show greater diffraction for smallerRefraction of water waves

When waves encounter obstacles like slits, they diffract or bend around the edges. Diffraction can be explained by Huygens' principle, which says each point on a wavefront acts as a new source. For a single slit, the new wavefront shape is determined by combining spherical wavelets from points across the slit. There are two types of diffraction: Fresnel, where distances are finite, and Fraunhofer, where incident waves are plane waves. X-ray diffraction uses wavelengths comparable to atomic sizes to determine crystal and molecular structures.Seismic Reflection

1) Wave interference occurs when two waves meet while traveling along the same medium, causing the medium to take on a shape resulting from the net effect of the individual waves.
2) Constructive interference occurs when wave displacements are in the same direction, like two crests or two troughs meeting, increasing displacement. Destructive interference occurs when displacements oppose each other, like a crest and trough meeting, decreasing displacement.
3) When waves interfere according to the principle of superposition, the resulting displacement at each location is the algebraic sum of the individual displacements. This can produce standing wave patterns with points of no displacement called nodes and maximum displacement called antinodes.Interference of light

Waves can interfere when they overlap in space. Constructive interference occurs when wave amplitudes add, increasing the overall amplitude. Destructive interference occurs when wave amplitudes subtract, decreasing the overall amplitude. When waves reflect off surfaces, the angle of incidence equals the angle of reflection according to the law of reflection. Refraction occurs when waves pass from one medium to another with a different speed, causing the waves to bend. Standing waves form when waves reflect back on themselves, creating nodes of no displacement and antinodes of maximum displacement.Interactions of waves11

Waves can interfere when they overlap in space. Constructive interference occurs when wave amplitudes add, increasing the overall amplitude. Destructive interference occurs when wave amplitudes subtract, decreasing the overall amplitude. When a wave encounters a boundary, it can be reflected. The angle of reflection is equal to the angle of incidence. Refraction occurs when a wave passes from one medium to another of different density, changing the wave's direction. Standing waves occur when a traveling wave is reflected back on itself, forming areas of maximum and minimum displacement.S4 E Phy Waves(Tranverse)(T)

Transverse waves transfer energy from one place to another without the physical transfer of the medium between the two points. Transverse waves are waves in which the particles of the medium move at right angles to the direction of wave motion. The key characteristics of transverse waves are that the particles vibrate perpendicular to the direction of wave propagation, and properties like amplitude, wavelength, frequency, and speed can be used to describe wave behavior.Light waves

Waves can be categorized as mechanical or electromagnetic. Mechanical waves require a medium to travel through, while electromagnetic waves do not. Waves can also be transverse or longitudinal depending on the direction of particle oscillation relative to wave propagation. Important wave properties include amplitude, wavelength, frequency, and speed. Reflection, refraction, diffraction, interference, and polarization are key wave phenomena. Reflection follows the laws of reflection, while refraction follows Snell's law. Diffraction and interference result in constructive and destructive patterns. Polarization occurs when waves vibrate in a single plane. Waves have many applications including ultrasound imaging, fiber optics, and 3D displays.3.1 form 4 general wave properties

Waves are disturbances that transfer energy through a medium from one point to another as vibrations. There are two main types of waves: transverse waves, where the vibration is perpendicular to the direction of motion, and longitudinal waves, where the vibration is parallel. Waves can be characterized by their wavelength, frequency, amplitude, and speed. The relationship between wavelength, frequency, and speed is described by the wave equation, which can be rearranged into different forms using a formula triangle. Waves undergo various interactions as they travel, including reflection, refraction, and diffraction.Ad
