Question

a traveling wave is described by Y(x,t)=c*e^[4i(2ax-bt)]
How may I calculate the velocity of the wave?

Answer 1

partial differentiation?

Answer 2

well i am under the impression that it has something to do with the wave number and the angular frequency

Answer 3

sorry, can't help you here.

Answer 4

For the celerity of the wave, hunt for the phase. The phase is the part in brackets where time is.

Here, phase is : 4(2ax-bt)

Divide factor before t by factor before x: c = 4b/8a = a/2b
