Given: Progressive wave y=A text sin(kx-cot) When reflected by rigid wall progressive wave y=A sin [k(-x)-ω t] or y=A sin [-(kx+ω t)] or y=-A sin [kx+ω t]

Q. A progressive wave $y = A sin (k x - ω t)$ is reflected by a rigid wall at $x = 0$ . Then the reflected wave can be represented by

$y = A sin (k x + ω t)$

$y = A cos (k x + ω t)$

$y = - A sin (k x - ω t)$

$y = - A sin (k x + ω t)$

$y = A cos (k x - ω t)$

Given: Progressive wave $y = A s in (k x - co t)$
When reflected by rigid wall progressive wave
$y = A sin [k (- x) - ω t]$
or $y = A sin [- (k x + ω t)]$
or $y = - A sin [k x + ω t]$

Q. A progressive wave y=Asin(kx−ωt) is reflected by a rigid wall at x=0 . Then the reflected wave can be represented by

y=Asin(kx+ωt)

y=Acos(kx+ωt)

y=−Asin(kx−ωt)

y=−Asin(kx+ωt)

y=Acos(kx−ωt)

Given: Progressive wave y=Asin(kx−cot) When reflected by rigid wall progressive wave y=Asin[k(−x)−ωt] or y=Asin[−(kx+ωt)] or y=−Asin[kx+ωt]
