- Homework Statement
- A light wave of wavelength 800 nm is directed in the x-y plane at 45o. For this propagating wave, 1) what is the magnitude of the k-vector?_________rads/cm
2) what is the magnitude of the k-vector?_________rads/cm
- Relevant Equations
- magnitude = 2(pie)/(wavelength)
I didnt understand the question. The magnitude is 2(pie)/wavelength. I get 78500 rad/cm which is pretty wrong as guess. Where would angle come into picture?

Shouldn't direction be like i + j + k ?
So will it be like:
|k|cos30 i + |k| sin30 j + 0 k ?
