`y(x, t) = 0.8//[4x + 5t)^(2) + 5]` represents a moving pulse, where `x` and `y` are in meter and `t` in second. Then

A

Pulse is moving in+ x direction

B

In 2 s It will travel adistance of 2.5 m

C

Its maximum displacement is 0.16m

D

It is a symmetric pulse

Text Solution

Verified by Experts

The correct Answer is:
B, C
From the equation given the function of X and? when compared to (x + vt) we get the wave speed as 1.25 m/s and the wave has an amplitude of 0.8/5 = 0.16m.
