Question

A motion is described by y= 4ex(e-5t) where y, x are in metres and t is in second.

(A) This represents progressive wave propagating along – x direction with 5 m/*

(B) This represents progressive wave propagating along + x direction with 5 m/*

(C) This does not represent progressive wave.

(D) This represents standing wave.

Answer 1

Correct option (B) This represents progressive wave propagating along + x direction with 5 m/s

Explanation:

Therefore, the given wave represents progressive wave propagating along + x direction with 5 m/*.
