Two sinusoidal waves with same wavelengths and amplitudes travel in opposite directions along a string with a speed `10ms^-1`. If the minimum time interval between two instant when the string is flat is `0.5s`, the wavelength of the waves is

`25m`

`20m`

`15m`

`10m`

Text Solution

Verified by Experts

The correct Answer is:

Minimum time interval between two instant when the string is flat`=(T)/(2)=0.5secimpliesT=1sec`
Hence `lamda=vxxT=10xx1=10m`.
