Question

A periodic transverse waves is created by shaking one of a string side to side periodically.ten oscillations are completed in 2.00 seconds.It is known that the wave speed is 2.00 m/s. Calculate frequency of the wave, period of the wave and the wave length

Answer 1

$$T=t/N=0.2\text s.\\ f=1/T=5\text{Hz}.\\ \lambda=cT=2·0.2=0.4\text{ m}.$$
