Light and Sound Waves

What is diffraction?

• The bending of a wave when it passes at an angle from one medium to another

• The passage of light or sound through an object

• The bending of a wave when it moves around an obstacle

• Matter through which a wave travels

A sound wave does not require a medium to travel

• True

• False

What is an echo?

• A mechanical wave

• The bouncing back of a wave when it hits a surface that it cannot pass through

• When a wave’s energy is being reduced

• The result of a sound wave being reflected

What is a reflection?

• The bending of a wave when it moves around an obstacle

• The bouncing back of a wave when it hits a surface that it cannot pass through

• The passage of light or sound through an object
