reflection of light Flashcards
1
Q
what is a plane mirror
A
a type of mirror that is perfectly flat
2
Q
what does light consist of
A
waves
3
Q
what is an incident ray
A
the ray of light that hits the reflective surface
4
Q
what happens when plane waves reflect from a flat barrier
A
the reflected waves are at the same angle to the barrier as the incident waves
5
Q
what is the normal
A
the line perpendicular to the mirror
6
Q
what is the angle of incidence
A
the angle between an incident ray and the normal
7
Q
what is the angle of reflection
A
the angle between the reflected ray and the normal
8
Q
for any light ray reflected by a plane mirror:
A
angle of incidence = angle of reflection
