Question

Given a 3 GHz wave traveling in free space at angles 30o α = , 60o β = , 90o γ = with respect to the x, y, and z axes. Find an expression for (a) the wave vector k (b) the wave number k

Answer 1

Answer:

a

The expression for wave number is   $k = 10\pi(\sqrt{3}\ a_{x} +a_{y})$

The expression for the wave number is  $B = \frac{2\pi}{wavelength } = \frac{2\pi}{0.1} =20\pi$
