This document discusses total internal reflection (TIR). It defines TIR as occurring when light enters a medium with a lower optical density at an angle greater than the critical angle, causing it to be totally reflected back rather than refracted. It presents three cases of a light ray entering from a denser to rarer medium and describes how TIR applies in the third case when the incident angle exceeds the critical angle. Examples where TIR occurs include the formation of rainbows, the luster of diamonds, mirages, and optical fibers.Ppt

Total Internal Reflection and Critical AngleAmit Raikar
油
This document discusses total internal reflection and the critical angle. It defines refractive index as the ratio of light speed in a vacuum to light speed in a medium. When light passes from one medium to another of different density, refraction occurs. As the angle of incidence increases, so does the angle of refraction, until reaching the critical angle. At the critical angle, the light ray follows the surface instead of entering the second medium. Above the critical angle, total internal reflection occurs and the light is reflected back into the first medium. Total internal reflection and critical angles depend on the refractive indices of the materials, and have applications in fiber optics, prisms, periscopes, and more.Total internal reflection (3)

This document discusses total internal reflection and its applications. Total internal reflection occurs when light travels from an optically denser medium to a less dense medium at an angle greater than the critical angle, causing the entire light ray to be reflected back into the denser medium. This phenomenon is used in applications like mirages, optical fibers, and cutting diamonds to maximize their brilliance. Optical fibers use total internal reflection to transmit light along their length, and the facet cuts of diamonds are designed to produce total internal reflection and make the diamond sparkle.Total internal reflection

The document discusses the principles of light propagation in optical fibers, including total internal reflection. It explains that total internal reflection occurs when light travels from a higher density medium to a lower density medium at an angle greater than the critical angle. This causes the light ray to reflect back into the first medium rather than refracting into the second. Total internal reflection is the mechanism that allows light to propagate along the length of an optical fiber with little loss of intensity.Refraction of Light

The document provides an overview of interference and diffraction concepts. It discusses interference due to thin films of uniform and non-uniform thickness. For thin films of uniform thickness, the conditions for constructive and destructive interference are derived based on the total path difference being equal to integral or half-integral multiples of wavelength. For wedge-shaped thin films of non-uniform thickness, the optical path difference expression is derived and the conditions for bright and dark fringes are obtained. Key features of interference patterns from wedge-shaped films like equidistant, straight and parallel fringes are also summarized.Refraction

This document discusses key concepts related to the refraction of light, including:
- Refraction occurs when light passes from one medium to another, changing direction as it enters the new medium. The degree of bending depends on the optical density of the materials.
- Two laws govern refraction: Snell's law states that the ratio of sines of the angles of incidence and refraction is a constant; and the law of refraction states that the incident ray, refracted ray, and normal all lie in the same plane.
- The refractive index is a measure of how much light bends when entering a material, and depends on the material's optical density - the higher the density, the greater the refractive indexTotal internal reflection (3)

This document discusses total internal reflection and some of its applications. Total internal reflection occurs when light travels from an optically denser medium to a less dense medium at an angle greater than the critical angle, causing the entire light ray to be reflected back into the denser medium. This phenomenon is used to create mirages by light rays curving downward in air of varying densities near the ground. Optical fibers are also able to transmit light along their length due to total internal reflection of light off the fiber walls. Cut diamonds are designed to take advantage of total internal reflection to reflect light internally and appear brilliant.Interference of light presentation

1. Interference occurs when two or more coherent light waves superimpose, resulting in variations in the intensity of the combined wave. Constructive interference occurs when path differences are equal to integral multiples of the wavelength, producing maximum intensity, while destructive interference occurs when path differences are equal to odd multiples of half the wavelength, producing minimum intensity.
2. Young's double slit experiment demonstrates interference through the use of two slits that act as independent coherent sources. The interference pattern produced on a screen shows alternating bright and dark fringes. The width of the fringes is directly proportional to the wavelength of light and inversely proportional to the slit separation.

The document discusses the laws of reflection and refraction of light. It states that the angle of incidence equals the angle of reflection, and that light bends when changing mediums due to changes in velocity. The index of refraction is a value that indicates how much a substance bends light. Snell's law states that the index of refraction of the incident medium times the sine of the angle of incidence equals the index of refraction of the refracted medium times the sine of the angle of refraction. An example calculation is shown to find the index of refraction of plexiglass using measurements and air's known index of refraction.2 interference and diffraction

Wave optics explains phenomena like interference and diffraction that are observed when light behaves as a wave. Interference occurs when two light waves superimpose, with constructive interference creating bright fringes and destructive interference creating dark fringes. Young's double slit experiment demonstrated this by passing light through two slits and observing the resulting interference pattern of alternating bright and dark bands on a screen. The conditions for interference are that the light sources must be coherent and have the same wavelength. [END SUMMARY]06 partial refraction and total internal reflection

This document discusses the optical phenomena of partial refraction, total internal reflection, and their applications. It explains that as the angle of incidence increases at a boundary between two media, more light will be reflected and less refracted in a phenomenon called partial reflection and refraction. It also defines total internal reflection as occurring when the angle of incidence passes the critical angle and light can only travel from a denser to less dense medium by fully reflecting rather than refracting.

Optics involves the reflection and refraction of light. Reflection occurs when light bounces off a surface, following the law of reflection where the angle of incidence equals the angle of reflection. Refraction is when light changes speed and direction when passing from one medium to another due to a change in index of refraction. Refraction is described by Snell's law, where the ratio of sines of the incident and refracted angles is equal to the ratio of the indices of refraction. Total internal reflection occurs when light passes from a higher to lower index of refraction beyond the critical angle and is completely reflected rather than refracted.Image formation in lens

2. Fraunhofer diffraction occurs when there is a planar wavefront and the observation is at infinity, producing fixed diffraction patterns. Fresnel diffraction involves cylindrical wavefronts and a finite observation distance, producing patterns that change as you propagate downstream.
3. In single-slit diffraction, the intensity at the center maximum is highest, while the principal minima occur when the path difference is equal to odd multiples of half the wavelength. Secondary maxima occur at positions satisfying the condition derived by equating the intensity equation to zero.Optics basics concepts

La primera actividad explica el dise単o de un generador de tono de audio que puede generar una onda senoidal de 1 kHz o 2 kHz usando un oscilador con amplificador operacional. La segunda actividad detalla el dise単o de un modulador PWM de 200 Hz y 60% de ciclo de trabajo usando dos temporizadores LM555. La tercera actividad consiste en mezclar las se単ales de audio y video mediante un amplificador no inversor con dos entradasAutomatic Breaking System

Automatic Braking System (ABS) uses sensors to detect wheel lockup during braking and selectively applies and releases brake pressure to prevent skidding and maintain steering control. It has several components including wheel speed sensors, an electronic control unit, hydraulic control unit, and brake master cylinder. ABS provides advantages like maintaining vehicle control during braking and is safer and more effective than regular braking, but it also has higher costs.Ad
