15.2 Reflection Flashcards
1
Q
What are the two rules of reflection that apply to all surfaces?
A
- incident ray and reflected ray lie in a single plane that is perpendicular to surface(the normal)
- the incidence angle is equal to angle of reflection
2
Q
What are the three things that can happen when a wave meets a boundary of another media?
A
can be reflected, transmitted or absorbed
3
Q
What is the incidence ray?
A
The wave oncoming onto the surface
4
Q
What is the incidence angle?
A
the angle at which the incidence ray meets the surface
5
Q
What is the reflected ray ?
A
The ray which leavs after reflection
6
Q
What is the reflected angle?
A
The angle at which the reflected ray leaves after meeting the surface
7
Q
What does the fraction of wave reflected depends on?
A
The medium being hit by the wave and the incidence angle
8
Q
Would the fraction of reflection usually increase when angle is made greater?
A
yes
