Question

InE=E notsin(kx-omega t) what is x?​

Answer 1

We know that in a wave equation y=Asin(ωt+kx+ϕ)y=Asin⁡(ωt+kx+ϕ),

yy = Displacement of particle on y-axis (assuming transverse wave)

AA = Amplitude

ωω = Angular velocity

kk = wave number and

ϕϕ = phase difference

I understand that the everything within the bracket in the equation is an angle. But I dont understand what is the difference between those terms. When do we use ωtωt and kxkx and ϕϕ?

As much as I understand ϕϕ is taken into account when we need to find the angle difference between two waves. But I am really confused between the other two. Is there even any difference between both of them?
