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