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.

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 :

Where,

is frequency

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".                     

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
