When light propagates from a material with a given index of refraction into a material with a smaller index of refraction, the speed of light

What is the minimum value that the index of refraction can have?

etc …

Part A = 24.09°

Part B = 60.97°

A beam of white light is incident on the surface of a diamond at an angle θ_{a}.

Find θ_{crit}.

For α = 45°, find the incident angle θ_{a} such that the blue light is totally internally reflected off the bottom surface.

A certain crystal gives a deflection angle of 22° for the first-order maximum of monochromatic X-rays with a frequency of 1.9*10^17 Hz.

What is the lattice spacing of the crystal?

Part A = Yes

Part B = 123 nm

Part C = 211 nm

A solar cell is designed to have a nonreflective film of a transparent material for a wavelength of 590 nm.

Will the thickness of the film depend on the index of refraction of the underlying material in the solar cell?

If n_{solar} > n_{film} and n_{film} = 1.20, what is the minimum thickness of the film?.

Repeat the calculation in Part C if n_{solar} < n_{film} and n_{film} = 1.40.

Part A = red

White light passes through a piece of crown glass and strikes an interface with air at an angle of 41.15°. The index of refraction of crown glass is 1.515 for red light and 1.523 for blue light.

Which color(s) of light will be refracted out into the air?

Part A = Yes

Part B = No

A 45° – 90° – 45° prism (see the figure) is made of a material with an index of refraction of 1.85.

Can the prism be used to deflect a beam of light by 90° in air?

What about in water?
