Light Waves

Front

Behavior that light waves cannot undergo at a boundary between two media: stopping at the edge of the boundary, reflection off of the boundary, transmission into the boundary, refraction through the boundary.

Back

stopping at the edge of the boundary

Front

Refraction is to:

Front

What does LASER stand for?

Back

Light Amplification by Stimulated Emission of Radiation

Front

Suppose you shine a laser directly at a mirror so that the laser strikes it perpendicularly. The angle of reflection is 0.5°. What does this tell you about the mirror?

Back

The mirror’s surface is not perfectly flat. It is angled 0.5° in the location that the laser is striking.

Front

Who built the first laser, and when?

Back

Theodore H. Maiman in 1960

Front

Which of the following IS NOT a component of a laser?

fuel injector

,

gain medium

,

high reflector

,

output coupler

Back

fuel injector

Front

What is the relationship between the angle of incidence and the angle of reflection when a light ray strikes a smooth, flat surface?

Back

They are equal.

Front

In this diagram, which is the angle of incidence?

Options: Angle A, Angle B, Angle C, Angle D

Back

Angle B

Front

How do light rays reflect off a concave mirror?

Back

Reflected rays converge toward the center line of a concave mirror.
