Explain, using math, why light can only undergo total internal reflection when propagating from an incident medium that has a higher refractive index than the medium from which the light is reflected (the potential transmitted medium), that is: ni > nt – the light must be bending away from the normal.
Make sure to include the “limits” of the sine function in your discussion.

2. Use Snell's law (n, sin = n, sine,) to explain why , is greater than 0 in Fig. 2. Total Internal Reflection When light passes from a medium of large refractive index into one of small refractive index --- for example, from water to air --- the refracted ray bends away from the surface normal, as shown in Fig. 2. As the angle of incidence increases, the angle of refraction also increases. When the angle of incidence reaches a...

1. Why is it not possible for total internal reflection to occur when a light beam is passing from a medium of low optical density (air) into a medium of higher optical density ( glass or water). Explain fully. 2. When light is incident on an interface between two materials, the angle of the refracted ray depends on the wavelength, but the angle of the reflected ray does not. Why should this be true? Explain fully. 3. Sunlight and star...

(2 points) Optical fibers are made of glass, where light is trapped inside the fiber by total internal reflection. This example is not a fiber geometry and doesn't include the gradations in refractive index that are used, but still illustrates the point of total internal reflection. Suppose you have a piece of glass, with light incident from the glass side toward an air interface. The refractive index of the glass is 1.45. What is the critical angle where all light...

Suppose you are using total internal reflection to make an efficient corner reflector - that is, a material shaped so that the light is reflected back towards its source. For example, each one of the prisms in the binocular shown is a corner reflector. θ = 32 ° If there is air outside and the incident angle at the first glass-air interface is 32° with respect to the normal, what must be the minimum index of refraction, nmin, of the...
