The equation of a progressive wave is `y=8 sin [ pi ((t)/(10)-(x)/(4))+(pi)/(3)]`. The wavelength of the wave is

A

2m

B

4m

C

8m

D

16m

Text Solution

Verified by Experts

The correct Answer is:
C
`y = 10 sin [2pi ((t)/(20) - (x)/(8)) + (pi)/(3)]` on comparing with
`y = A sin 2pi ((t)/(T) - (x)/(lamda))` we get `lamda = 8m`
