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

A

8 m

B

4 m

C

2 m

D

10 m

Text Solution

Verified by Experts

The correct Answer is:
A
`x = 8 sin [pi ((x)/(10) - (x)/(4)) + (pi)/(3)]`
`k = (pi)/(4)`
`(2pi)/(lamda) = (pi)/(4) " " :. lamda = 8 m`
