Wave Properties

Which property of the wave does the value of two per second describe?

• wavelength

• intensity

• frequency

• amplitude

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?

• 1.33 Hz

• 3.00 Hz

• 0.75 Hz

• 3.50 Hz

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 increased to four times the original energy.

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

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

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

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 longer wavelength.

• has a shorter wavelength.

• has a greater amplitude.

Two waves are traveling through a tube. Wave X has an amplitude of 1 cm, and wave Y has twice the amplitude of wave X. The energy of wave Y is

• four times that of wave X.

• half times that of wave X.

• two times that of wave X.

• one-fourth times that of wave X

Garrett throws a large rock into a waveless pond. The impact of the rock hitting the water causes waves to travel along the pond's surface toward the shore.

If Garrett counts the number of waves that reach the shore over a 10‑second period, what property of the waves is he measuring?

• frequency

• speed

• amplitude

• wavelength
