Question

A sound wave has a wavelength of 0.450 meters if it’s speed in cold air is 330 meters per second what is the wave’s frequency

Answer 1

733.3Hz

Step-by-step explanation:

V=fx

where V is velocity of sound wave ; 330m/s

f is frequency of sound wave ; unknown

x is wavelength of sound wave; 0.450m

substituting the values

V=fx

330=0.450f

f=733.3
