Homework Statement
The direction of propagation is defined as ex=sin(theta)cos(phi), ey=sin(theta)sin(phi), ez=cos(theta). What are the values of theta and phi characterizing the direction of propagation?
Homework Equations
We have a point in space with the coordinates (r,theta,phi)=(2,3,4)
Components were defined in the problem.
The Attempt at a Solution
Well, seeing as how the point is being designated by these numbers, and according to the spherical notation these numbers should represent theta and phi, I would think the answer would be theta=3 and phi=4. But that seems way too easy... so any guidance would be appreciated.
Thank you in advance!
