Wave Properties and Behavior Quiz - PS

When a wave moves from air into water, which of the following occurs?

• The wave maintains its original path

• The wave is completely reflected

• The wave is refracted away from the normal line

• The wave is refracted toward the normal line

The number of wavelengths that pass a point in a given amount of time is called:

• Amplitude

• Period

• Frequency

• Wavelength

Which of the following best explains acoustic resonance?

• The amplification of sound waves when wave frequency matches the natural frequency of an object

• The reflection of sound waves when they hit a hard surface

• The ability of sound waves to travel faster in solids than in air

• The change in sound wave direction when moving between different mediums

What happens to a wave's frequency when its wavelength decreases?

• The frequency decreases

• The frequency increases

• The frequency stays the same

• The frequency becomes zero

____ P waves (primary waves) are longitudinal waves that move particles parallel to the direction of wave energy.

• True

• False

____ All types of waves require a medium to travel through.

• True

• False

____ A higher frequency tuning fork will create acoustic resonance in a shorter air column compared to a lower frequency tuning fork.

• True

• False

Match the following

• Frequency

• A point where a standing wave has zero amplitude

• Amplitude

• The change in a wave's direction when it passes from one medium to another

• Reflection

• When a wave bounces back after hitting a boundary

• Refraction

• The maximum displacement of a medium from its rest position

• Node

• The number of complete wave cycles passing a point per unit time
