A) \[y=A\sin (kx+\omega t)\]
B) \[y=A\cos (kx+\omega t)\]
C) \[y=-A\sin (kx-\omega t)\]
D) \[y=-A\sin (kx+\omega t)\]
E) \[y=A\cos (kx-\omega t)\]
Correct Answer: D
Solution :
Given: Progressive wave \[y=A\text{ }sin(kx-cot)\] When reflected by rigid wall progressive wave \[y=A\sin [k(-x)-\omega t]\] or \[y=A\sin [-(kx+\omega t)]\] or \[y=-A\sin [kx+\omega t]\]You need to login to perform this action.
