Q
Waves behave differently when they encounter different types of matter (called mediums).
Identify and explain at least 2 wave behaviors.
A
Reflection is when a wave bounces off new medium
Refraction is when a wave enters a new medium and changes direction and speed (light traveling from air to water)
Absorption is when some of the waves energy is trapped within a medium and the wave is weakened.
Diffraction is when the wave energy bends around an obstacle
