Reflection Flashcards
1
Q
What are light waves also called?
A
Light rays
2
Q
What is specular reflection?
A
A mirror’s smooth shiny surface allows each light ray to reflect at the same angle. giving a clear reflection
3
Q
What is diffuse reflection or diffuse scattering?
A
Rough surfaces are dull so light rays are scattered. (reflected in different directions)
4
Q
What is the law of reflection?
A
Angle of incident = angle of reflection
Angle i = angle of r
5
Q
Where is the angle of incident and angle of reflection always measured between?
A
Between the light ray and the normal.
6
Q
What is the normal?
A
Line at a right angle (90°)
7
Q
Draw the diagram and label it
A
Shiny side of mirror/ dull side of mirror, normal, Reflected light ray (angle r) –<— and incident light ray (angle i) —>–
