Image Sensors
Law of Reflection:
“Angle of Incidence = Angle of Reflection”

Law of Refraction
“Snell’s Law”:
Refraction Example:
A light ray starts in a medium with index of refraction n1 and goes into a medium with index of refraction n2. The angle of incidence is 1. The angle of refraction (transmission) is 2.
a) If n1 < n2, where is the light ray traveling fastest?
b) If n1 < n2, which is larger, 1 or 2?
c) A beam of light is incident on the interface between plastic (n = 1.3) and air with a 40o angle as shown.
What is the angle of the refracted ray?
40o
plastic
air
