The Behavior of Waves Mastery

1. Reflection occurs when a wave _________________.

• strikes an object and bounces off of it

• passes through an object and continues

• is absorbed by an object

• changes its frequency

2. ________________ is the bending of a wave caused by a change in its speed as it travels from one medium to another.

• Refraction

• Reflection

• Diffraction

• Absorption

3. ________________ occurs when waves bend around a barrier.

• Diffraction

• Reflection

• Refraction

• Absorption

What happens when two waves pass through each other?

• They cancel each other out completely.

• They reflect off each other.

• They interfere with each other.

• They merge into a single wave.

The main reason that a standing wave occurs is because _________________

• waves of equal wavelength and amplitude that travel in different directions continuously interfere with each other

• the medium through which the wave travels is perfectly elastic

• the frequency of the wave is too high for the medium

• the wave loses energy as it travels through the medium
