Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which phenomenon best describes the bending of light as it passes from one medium to another?
Reflection
Diffraction
Refraction
Absorption
2. According to Snell's Law, when light passes from a less dense medium to a more dense medium, it bends:
Away from the normal
Towards the normal
Parallel to the normal
Does not bend
1. The ratio of the speed of light in a vacuum to the speed of light in a medium is called the .
2. When light travels from a denser medium to a rarer medium, and the angle of incidence exceeds the critical angle, occurs.
1. State Snell's Law and define all the terms used.
Observe the diagram below showing light refracting as it enters water. Label the incident ray, refracted ray, normal, angle of incidence, and angle of refraction.
1. The frequency of light changes when it undergoes refraction.
True
False
2. Dispersion of light is a phenomenon caused by the refraction of different wavelengths of light at different angles.
True
False
1. A light ray enters a block of glass (n = 1.52) from air (n = 1.00) at an angle of incidence of 30°. Calculate the angle of refraction.
