Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Which of the following best describes light refraction?
The bending of light as it passes from one medium to another.
The reflection of light off a surface.
The spreading of light waves.
The absorption of light by a material.
2. Snell's Law relates the angles of incidence and refraction to the:
Wavelengths of light.
Frequencies of light.
Refractive indices of the media.
Amplitudes of light waves.
3. The critical angle is the angle of incidence beyond which total internal occurs.
4. When light passes from a less dense medium to a more dense medium, it bends the normal.
5. A light ray passes from air (n=1.00) into glass (n=1.52) at an angle of incidence of 30 degrees. Calculate the angle of refraction.
6. Observe the diagram below showing light entering water. Describe what is happening to the light ray at the interface between air and water.
7. Total internal reflection can occur when light travels from a more optically dense medium to a less optically dense medium.
