Wave Properties Quiz

An oscilloscope can be used to produce visible pictures of sound waves. If an oscilloscope is used to measure the distance between the crests of a sound wave, what property of the wave will it be measuring?

• wavelength

• loudness

• frequency

• amplitude

The speed of a sound wave traveling through air is 400 meters per second. The wavelength of the wave is 25 meters. What is the frequency of the wave?

• 16 hertz

• 0.0625 hertz

• 425 hertz

• 10,000 hertz

What is a wave frequency?

• the loudness of a wave as it travels though the air

• the number of waves that pass a fixed point in a fixed period of time

• the height of a wave between peak and trough

• the speed that a wave is passed from particle to particle through a medium

Water waves are hitting against a boat. If the frequency of water waves is reduced to one-third of the original frequency, what happens to the energy transferred to the boat?

• The energy transferred to the boat is reduced to one-half of the original energy.

• The energy transferred to the boat is increased to four times the original energy.

• The energy transferred to the boat is reduced to one-third of the original energy.

• The energy transferred to the boat is increased to nine times the original energy.

A machine produces compression waves in a spring that is 120 cm long by pulsing twice every second. The back and forth movement of the pulse creates compressed sections of the spring that are 30 cm apart and travel toward the other end of the spring. Which property of the wave does the value of two per second describe?

• amplitude

• wavelength

• frequency

• intensity

Donna wants to calculate the speed at which a sound wave is traveling. She knows that the frequency of the wave is 680 hertz and that the wave has a wavelength of 0.5 meters. The speed of the sound wave is _ m/s.

(a)  

Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X

• has a lower amplitude.

• has a greater amplitude.

• has a longer wavelength.

• has a shorter wavelength.

Jake calculates that the frequency of a wave is 230 hertz and that the wave is moving at 460 m/s.

The wavelength of the wave is _ m.

A red light source emits light of a certain frequency. A violet light source emits light that has double the frequency of the red light source. How does the wavelength of the red light compare to the violet light.

• The red light's wavelength is twice that of the violet light.

• The red light's wavelength is four times that of the violet light.

• The red light's wavelength is half that of the violet light.

• The red light's wavelength is the same as the violet light.

Ms. Lawson is making a video about waves. In the video she wiggled a string to create a transverse wave. The wave had a wavelength of 2.0 m and speed of 1.5 m/s. What was the frequency of the wave?

• 0.75 Hz

• 3.50 Hz

• 1.33 Hz

• 3.00 Hz
