They can reflect, refract, or be absorbed
When a wave bounces off a material boundary
angleofincidence=angleofreflectionangle of incidence = angle of reflectionangleofincidence=angleofreflection
Angle between incoming wave and normal line
Angle between reflected wave and normal line
Line drawn perpendicular to the boundary
Waves bounce off smooth surface at same angle, clear reflection
Waves hit rough surface, reflect at diff. angles, matte look
Waves change direction crossing between materials
When wave meets boundary at an angle
Bends away from the normal
Bends toward the normal
Typically slower in denser materials
Travel faster (exception to usual rule)
