Length of a string tied to two rigid support is `40cm`. Maximum length (wavelength in cm) of a stationary wave produced on it is

A

20

B

80

C

40

D

120

Text Solution

Verified by Experts

The correct Answer is:
B
In fundamental mode of vibration wavelength is maximum `impliesl=(lamda)/(2)=40cmimplieslamda=80cm`
