Waves Review

The wavelength of a wave is doubled when the frequency remains the same. What happens to the speed of the wave? (v = λf)

• It doubles

• It quadruples

• It remains unchanged

• it is cut to one half

• it is cut to one fourth

The distance between crests of a wave decreases. What happens to the frequency if the speed remains constant? (v = λf)

• It increases

• It remains the same

• It decreases

• It is cut in half

• It is cut in a quarter

Which of the following statements is true about longitudinal waves?
