A) Starting with n1 Sin i = n2 Sin r, show that
the value of i when r = 90 degrees is given by
sin-1(n2 / n1). This value of i is
usually designated as ic, the angle for total internal
reflection.
B) For what condition on n1 and n2 does this
expression make sense?
I know how to solve for A, but I'm lost on part B, can you
please show me how we find the condition and the...

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...

How does total internal reflection work and what are some examples of where you would observe it? How does dispersion work and what are some examples of where you would observe it? How does the focal length behave in terms of wavelenght, aberration, concave and convex mirros, and in converging and diverging lenses? What is a coherent wave and what are the sources of coherent 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...
