Interactions of Waves Quiz

What is reflection of waves?

• The amplification of waves when they encounter a boundary or obstacle.

• The bending of waves as they pass through a medium.

• The bouncing back of waves when they encounter a boundary or obstacle.

• The absorption of waves by a boundary or obstacle.

What is refraction of waves?

• The bending of waves as they pass from one medium to another due to a change in their speed.

• The absorption of waves by a medium.

• The reflection of waves off a surface.

• The amplification of waves as they pass through a medium.

What is diffraction of waves?

• The merging of waves as they pass through an opening or around an obstacle.

• The reflection of waves as they pass through an opening or around an obstacle.

• The absorption of waves as they pass through an opening or around an obstacle.

• The bending or spreading out of waves as they pass through an opening or around an obstacle.

What is interference of waves?

• The phenomenon that occurs when two or more waves cancel each other out.

• The phenomenon that occurs when waves pass through each other without interacting.

• The phenomenon that occurs when waves change direction as they pass through a medium.

• The phenomenon that occurs when two or more waves meet and combine to form a new wave.

What are standing waves?

• A type of wave pattern that occurs when two waves of different frequencies and amplitudes interfere with each other.

• A type of wave pattern that occurs when a wave reflects off a surface and interferes with the original wave.

• A type of wave pattern that occurs when two waves of the same frequency and amplitude traveling in opposite directions interfere with each other.

• A type of wave pattern that occurs when two waves of the same frequency and amplitude reinforce each other.

When does reflection of waves occur?

• When a wave encounters a boundary or obstacle and bounces back

• When a wave changes its frequency

• When a wave travels in a straight line

• When a wave passes through a medium

When does refraction of waves occur?

• When a wave passes from one medium to another

• When a wave travels in a straight line

• When a wave passes from one medium to another

• When a wave is absorbed by a medium

When does diffraction of waves occur?

• When a wave encounters an obstacle or passes through a narrow opening

• When a wave passes through a medium with high density

• When a wave travels in a straight line

• When a wave encounters a large opening

When does interference of waves occur?

• When waves travel in a straight line

• When two or more waves meet at the same point in space and time.

• When waves are absorbed by a medium

• When waves are reflected by a surface

What causes standing waves?

• Interference of waves traveling in opposite directions with the same frequency and amplitude

• Standing still in water

• The rotation of the Earth

• The phase of the moon
