Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. What phenomenon occurs when light passes from one medium to another and changes direction?
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
Does not bend
Reflects internally
1. The refractive index of a vacuum is less than 1.
True
False
2. Total internal reflection occurs when light travels from a more optically dense medium to a less optically dense medium.
True
False
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 enters a medium with a higher refractive index, its speed .
1. State Snell's Law in words and as a mathematical formula.
2. Explain the conditions necessary for total internal reflection to occur.
Observe the diagram below showing light entering water. Analyze the path of light and answer the questions that follow.
1. Is the angle of refraction greater than or less than the angle of incidence in the diagram?
2. What does this tell you about the optical density of water compared to air?
