If a wave is traveling at 200 m/s and its wavelength is 0.5 meters, what is the frequency of the wave?

The frequency of the  wave = 400/s

Given

v=200 m/s

λ=0.5 m

Required

The frequency of the  wave

Solution

Frequency (f): number of waves in one second

The frequency is inversely proportional to the wavelength

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
