PS Wave Behavior HW

Front

What is reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a barrier or surface.

Front

Which figure represents reflection?

Back

Figure B represents reflection.

Front

What is diffraction in wave behavior?

Back

Diffraction is the bending of waves around obstacles or through openings.

Front

What type of wave behavior is shown in the image?

Back

The image shows diffraction.

Front

What is refraction in wave behavior?

Back

Refraction is the change in direction of a wave as it passes from one medium to another.

Front

What happens during refraction?

Back

The wave changes speed and direction when entering a different medium.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material.

Front

What is transmission in wave behavior?

Back

Transmission is the passing of waves through a medium without being absorbed.

Front

How do orcas use reflection?

Back

Orcas use reflection of sound waves to locate food.

Front

What do we hear when a sound wave reflects?

Back

When a sound wave reflects, we hear an echo.
