Question

If you double the wavelength of a wave on a string, what happens to the wave speed and the wave frequency ? Group of answer choices a) v is unchanged and f is halved. b) v is doubled and f is doubled. c) v is doubled and f is unchanged. d) v is unchanged and f is doubled. e) v is halved and f is unchanged.

Answer 1

Answer:

option (c)

Explanation:

the relation between the wavelength, frequency and wave velocity is given by

velocity = wavelength x frequency

As the wavelength is doubled, the frequency remains constant as it is the property of source.

So, the velocity becomes doubled.

Option (c) is true.
