- Refractive index and Snell's law
A light ray travels from air (n = 1.00) into a sheet of transparent plastic at an angle of incidence of 40.0°. The light ray refracts at an angle of refraction of 22.9°. - Snell's law with layers of different media
A light ray travels from air (n = 1.00) into a sheet of diamond (n = 2.42) with an angle of incidence of 25.0°. It passes through a second layer of acrylic (n = 1.49), then back into air. What is the angle of refraction:- In diamond?
- In acrylic?
- In air, when it comes out the other side?
