Calculate the frequency of a wave whose speed is 400 m/ s and wavelength is 80cm

Answer 1

Given;

speed(v)= 400m/s

wavelength(w)= 80cm= 0.8m

Using the formula v=fw;

0.8= f× 400

f= 0.8/400

f=0.002 hz

Hope this helped u!!

Answer 2

speed = wavelength /frequency

400m/s = 0.8/v
v= 0.8/400
v= 0.002 Hz
