Question

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
A.
has a lower amplitude.
B.
has a shorter wavelength.
C.
has a longer wavelength.
D.
has a greater amplitude.

Answer 1

Answer:

Wave X has a shorter wavelength.

Explanation:

It is given that, two sound waves (wave X and wave Y) are moving through a medium at the same speed.

Speed of a wave is given by :

$v=\nu\times \lambda$

Where,

$\nu$ is frequency

$\lambda$ is wavelength

The relation between the frequency and the wavelength is inverse. Wave X has greater frequency than Y, then wave X has a shorter wavelength.

Hence, the correct option is (B) "has a shorter wavelength".
