Equation of a progressive wave is given ...

Equation of a progressive wave is given by `y= a sin pi [(t)/(2)-(x)/(4)]`, where t is in seconds and x is in meters. The distance through which the wave moves in 8 sec is (in meter)

A

8

B

16

C

2

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
We use `v = (coefficent of t)/(Coefficent of x) = (1//2)/(1//4) = 2m//s`
Hence ` d = vt = 2 xx 8 = 16 m.
