The document discusses various characteristics and properties of waves, including:
1. Waves transfer energy through a medium without transferring the medium itself. Particles in the medium oscillate or vibrate as a wave passes through.
2. Waves can be transverse, with oscillations perpendicular to the direction of travel, or longitudinal, with oscillations parallel to travel.
3. Key wave characteristics include wavelength, frequency, period, amplitude, and speed. The speed of a wave is calculated as its frequency multiplied by wavelength.
4. Electromagnetic waves include visible light as well as other types of radiation such as radio waves, microwaves, infrared, ultraviolet, X-rays and gamma rays. All electromagneticWaves

Okay, let's break this down step-by-step:
* Mr. H vibrates the snakey 32 times in 10 seconds
* So the frequency is 32/10 = 3.2 Hz
* There are 4 sections each occupied by an antinode
* Since there are nodes between each antinode, there must be 5 nodes total
* With 5 nodes, this is the 5th harmonic standing wave pattern
* The 5th harmonic has 6 nodes
* So the wavelength is the total length (6.2 m) divided by 6 nodes
* Wavelength = 6.2 m / 6 = 1.033 m
* Using the wave equation: Speed = Frequency x Wavelength
* Speed = 3Wave Motion

Stationary waves are produced by the superposition of two progressive waves of equal amplitude and frequency travelling in opposite directions. They have nodes where there is no displacement and antinodes where the displacement is at a maximum. In a stationary wave, the waveform does not move through the medium and energy is not carried away from the source. All particles between two nodes vibrate in phase.0.1 introduction to waves

A wave is a disturbance that propagates through a medium without transporting matter. Particles in the medium oscillate locally as the wave passes by but do not move with the wave. A mechanical wave requires a source of disturbance, a medium that can be disturbed, and a mechanism to transfer the disturbance. Mechanical waves include sound waves, water waves, and seismic waves. Properties of a wave include wavelength, amplitude, period, frequency, and wave speed. The period is the time for one wavelength to pass a point, and frequency is the inverse of period. Wave speed equals wavelength multiplied by frequency.Magnetic flux

- Magnetic flux (陸B) is a measure of magnetic field strength over an area, measured in webers (Wb). 陸B = BA, where B is magnetic field strength and A is area.
- According to Faraday's law of induction, any change in magnetic flux over time induces a voltage in a circuit. The faster the change, the greater the induced voltage.
- Lenz's law states that an induced current will flow in a direction that opposes the change causing it, in order to conserve energy. This explains the negative sign in Faraday's law.Momentum

Momentum is a quantity that expresses the motion of a body, equal to the product of its mass and velocity. The momentum of an object depends on its mass and velocity, with greater mass or velocity resulting in more momentum. The law of conservation of momentum states that in a closed system without external forces, the total momentum before and after an interaction will be the same. Examples include a person recoiling after firing a gun or moving backward when throwing an object off a skateboard. In collisions, the total momentum of the system is conserved and can be expressed mathematically as the sum of the momentum of the objects before equalling the sum after.Wave Properties

1. Electrostatic forces are caused by the attraction and repulsion of electric charges, such as when objects are rubbed together.
2. Atoms become charged when they gain or lose electrons, forming ions. The structure of the atom is such that electrons orbit a small, dense nucleus at relatively large distances.
3. Charged objects interact through electric fields and can attract or repel one another depending on whether their charges are opposite or the same. Applications of electrostatic forces include photocopiers, spray painting, and identifying atoms through spectroscopy.Pressure and buoyancy
Pressure and buoyancycharlietheteacher
油
Liquids and gases can exert pressure as forces. Pressure is defined as the force per unit area applied on a surface. Pressure increases with depth in a fluid and depends only on the height of the fluid. Archimedes' principle states that the buoyant force on an object equals the weight of the fluid displaced. An object will float if its density is less than the fluid it displaces, causing an upward buoyant force greater than its weight.Thermal Expansion
Thermal ExpansionYannah Hidalgo

Thermal expansion is the tendency of matter to change in volume in response to temperature changes. Thermometers use thermal expansion - liquids inside thermometers expand or contract and rise or fall depending on temperature. Other applications include bi-metallic strips in thermometers bending due to differing expansion of the two metals. Rail tracks can buckle due to thermal expansion of long sections. Materials expand when heated as particles move farther apart on average. The coefficient of thermal expansion quantifies a material's expansion relative to temperature change.Thermal physics

Thermal physics discusses kinetic molecular theory and Brownian motion. Heat is defined as the flow of energy from a warm object to a cooler object. Heat energy is the result of atomic/molecular movement in solids, liquids and gases. Temperature is a measure of heat energy, with higher temperatures indicating faster particle movement. Thermometers measure temperature using various methods like liquid expansion. Thermal conduction transfers heat through particle collisions, while convection transfers heat through fluid movement.

The document discusses different types of waves. It defines a wave as a traveling disturbance that transfers energy from one place to another. It describes two main types of waves: transverse waves, which oscillate perpendicularly to the direction of wave advance, and longitudinal waves, where particles of the medium move parallel to the propagation of the wave. Key wave properties discussed include vibration, amplitude, wavelength, crests, troughs, compression and rarefaction.wave motion
- 2. A wave is a vibratory disturbance through a material (medium) or space. Waves transfer energy without transferring mass.
- 3. No medium required. Travel at the speed of light . c = 3 x 108 m/s Examples: visible light, x-rays, infrared rays
- 4. MECHANICHAL WAVES Require a medium ex. Sound, water, waves in springs. Longitudinal waves Examples - sound, seismic s-waves Transverse waves Examples: light, seismic p-waves, water
- 5. TRANSVERSE WAVES Waves that move the medium at right angles to the direction in which the waves are traveling .
- 6. CREST AND TROUGH Crest: A point on the wave where the displacement of the medium is at maximum. Trough: A point on the wave where the displacement of the medium is minimum.
- 7. LONGITUDINAL WAVES Longitudinal waves have vibrations moving in the same direction that the wave is travelling in.
- 8. COMPRESSSION AND RAREFRACTION Compression: A region in a longitudinal waves where the particles are closest together. Rarefraction: A region in a longitudinal wave where particles are farthest apart.
- 9. PROPERTIES OF WAVES Amplitude Frequency Speed wavelength
- 10. AMPLITUDE Maximum distance the particles of the medium carrying the wave move away from their rest positions. Amplitude of a transverse wave is the maximum distance the medium moves up or down from its rest position. Amplitude of a longitudinal wave is a measure of how compressed or rarefied the medium becomes.
- 11. WAVELENGTH A wave travels a certain distance before it starts to repeat. The distance between two corresponding parts of a wave is its wavelength. Transverse measure from crest to crest or trough to trough. Longitudinal measure from one compression to the next.
- 13. The number of complete waves that pass a given point in a certain amount of time. Frequency measured in hertz
- 14. SPEED, WAVE LENGTH & FREQUENCY The speed, wavelength, and frequency of a wave are related to each other by a mathematical formula. Speed = wavelength x frequency Frequency = speed/wavelength Wavelength = speed/frequency
