Given that y = a sin ωt+bt+ct2 cost ωt.
The unit of abc is same as that of
y
yt
(yt)2
(yt)3
Unit of y is same as that of a, bt, and ct2.
y=a, b=yt, c=(yt)2∴ a×b×c=(yt)3
Which of the following two wave equations can form stationary wave?
(i) Y=Asin(ωt−kx)
(ii) Y=Acos(ωt−kx)
(iii) Y=Asin(ωt+kx)
(iv) Y=Acos(ωt+kx)
