2nd 9 Week Review Part 2

How do the particles move in a transverse wave?

• back and forth in the same direction as the wave

• the air molecules themselves do not move

• up and down at right angles to the direction of the wave

• in all directions

How do the particles vibrate in a longitudinal wave?

• back and forth in the same direction as the wave

• the air molecules themselves do not move

• at right angles to the wave

• in all directions

Which interval represents one full wavelength on the transverse wave?

• Point A to Point I

• Point E to Point I

• Point C to Point E

• Point F to Point H

If the wavelength of a wave continually increases, what can we assume about the frequency?

• It will stay the same.

• It will get higher.

• It will get lower.

• It will fluctuate.

If the amplitude of a sound wave was decreased, what would happen to the sound made by this wave?

• It would have a lower pitch.

• It would have a higher pitch.

• It would get softer

• It would get louder.

The interaction of waves combining and making the loudness of sound waves softer is called —

• destructive interference

• constructive interference

• crest enhancement

• frequency distribution

A student observes the point in a medium where a sound wave has maximum density. What is the student observing?

• The amplitude of the wave

• The compression of the wave

• The rarefaction of the wave

• The crest of the wave

A student places two equal frequency tuning forks side by side. He strikes one tuning fork, listens to its tone, and then quickly silences it. After silencing it, the student can still hear the tone because the second tuning fork has now begun to vibrate. What has occurred between the two forks?

• Frequency

• Resonance

• Amplitude

• Reflection

What do sound waves need to travel through?

• A vacuum

• A light

• A medium

• A wave

Which of the following electromagnetic waves has the lowest amount of energy?

• Gamma Rays

• Radio Waves

• Visible Light

• Ultraviolet Rays
