The equation of a progressive wave is given by
`y = 5 sin [pi ((t)/(5) - (x)/(10))] + (pi)/(6) m`
Then which one of the following is correct?

A

a = 10 m

B

`lamda = 20 m`

C

`T = 5s`

D

n = 5 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`y = 5 sin 2pi ((t)/(10) - (x)/(20)) m`
`a = 5m, T = 10S, lamda = 20 m, f = (1)/(10) Hz`
`:. lamda = 20`m is correct
