Question 1

Waves behave differently when they encounter different types of matter (called mediums).

Identify and explain at least 2 wave behaviors.

Answer 1

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
