What is reflection?
What is reflection?
When a wave hits a surface & bounces back into the original medium instead of passing through
What are the two types of reflection?
What are the two types of reflection?
Specular reflection and diffuse reflection
Surface type for specular reflection
Surface type for specular reflection
Smooth surface
Surface type for diffuse reflection
Surface type for diffuse reflection
Distorted, uneven surface
Angle in specular reflection
Angle in specular reflection
Same angle of reflection as angle of incidence
Angle in diffuse reflection
Angle in diffuse reflection
Different angle of reflection vs angle of incidence
