Question 119: Waves

Question

Which of the following equations represents a travelling wave?

Accepted Answer

Y = F(x, t)
For travelling wave y should be linear function of x and t and they must exist as (x $\pm$ vt)
Y = A sin (15x $-$ 2t) $ 	o $ linear function in x and t.

Answer

y = Ae
x
cos($\omega$t $-$ $	heta$)

Answer

y = Ae
$-$x
