Geometric Optics Flashcards
1
Q
Transparent
A
Light can be transmitted through an object
2
Q
Opaque
A
Light cannot pass through an object
3
Q
Refraction
A
The change in direction of a wave passing from one medium to another
Speed slows down
4
Q
Refractive index
A
The ratio of the speed of light in a vacuum to its speed in the material
5
Q
Law of reflection
A
The angle of incidence is equal to the angle of reflection
6
Q
Properties of light
A
Reflected
Absorbed
Transmitted
7
Q
Critical angle
A
The angle of incidence where the angle of refraction is 90*
8
Q
Conditions for total internal reflection
A
Travel from dense to less dense
Angle of incidence must be greater than critical angle
