Three wave behaviors at material boundaries
Three wave behaviors at material boundaries
Reflected, absorbed, or transmitted
Definition of reflection
Definition of reflection
Wave hits surface & bounces back into original medium
Angle of normal to boundary
Angle of normal to boundary
90 degrees
Law of reflection
Law of reflection
Angle of incidence = angle of reflection
Type of reflection on smooth surfaces
Type of reflection on smooth surfaces
Specular reflection
Type of reflection on uneven surfaces
Type of reflection on uneven surfaces
Diffuse reflection
Specular reflection: reflected vs incident angle
Specular reflection: reflected vs incident angle
Same angle
Diffuse reflection: reflected vs incident angle
Diffuse reflection: reflected vs incident angle
Different angle
Effect of smoother surface on reflected wave
Effect of smoother surface on reflected wave
Stronger reflected wave
Definition of transmission
Definition of transmission
Waves pass through transparent material
Definition of absorption
Definition of absorption
Light absorbed by electrons, reemitted as heat
When absorption occurs
When absorption occurs
When light frequency matches electron energy levels
Green object: which light reflected?
Green object: which light reflected?
Green light only, rest absorbed
