Sound Waves Quiz

What is the definition of Wave Length in the context of a sound wave?

• The distance between two consecutive crests or troughs in a wave.

• The height of a wave from the rest position.

• The number of waves that pass a point in one second.

• The maximum displacement of a wave from its rest position.

What does the amplitude of a sound wave represent?

• The pitch of the sound.

• The loudness or volume of the sound.

• The speed of the sound wave.

• The frequency of the sound wave.

How does frequency relate to the pitch of a sound?

• Higher frequency means lower pitch.

• Frequency has no effect on pitch.

• Higher frequency means higher pitch.

• Only amplitude affects pitch.

What is the crest of a wave?

• The lowest point of the wave.

• The highest point of the wave.

• The length of the wave.

• The speed of the wave.

What is the trough of a wave?

• The highest point of the wave.

• The lowest point of the wave.

• The length of the wave.

• The speed of the wave.

Which of the following best describes the relationship between wavelength and frequency?

• They are directly proportional.

• They are inversely proportional.

• They are unrelated.

• They are the same thing.

If the amplitude of a sound wave increases, what happens to the sound?

• It becomes higher pitched.

• It becomes lower pitched.

• It becomes louder.

• It becomes softer.

What unit is frequency measured in?

• Meters (m)

• Hertz (Hz)

• Decibels (dB)

• Seconds (s)

If two sound waves have the same frequency but different amplitudes, how do they differ?

• In speed

• In pitch

• In loudness

• In wavelength

What does a longer wavelength indicate about a sound wave's pitch?

• The pitch is higher.

• The pitch is lower.

• The pitch is unchanged.

• The pitch cannot be determined by wavelength alone.
