Is "The Wave" at the stadium a transverse wave or a longitudinal wave?
A wave on a stretched drum head is an example of a:
The electric field for a plane wave is given by:
E(r,t)=E0ei(k⋅r−ωt)
The vector k tells you:
The electric field for a plane wave is given by:
E(r,t)=E0ei(k⋅r−ωt)
Suppose E0 points in the +x direction. Which direction is this wave moving?
A wave is moving in the +z direction:
f(x, y, z, t) = Re\left[A e^{i(kz – \omega t + \delta)}\right]
The value of f at the point (0,0,z_0, t) and the point at (x, y, z_0 , t) are related how?
f_1 = f (0,0,z_0 , t) vs. f_2 = f(x, y, z_0 , t)
