Homework Statement
Provide an expression in Cartesian coordinates for a plane wave of amplitude 1 [V/m] and wavelength 700 nm propagating in u = cosθx + sinθy direction, where x and y are unit vectors along the x and y-axis and θ is the measured angle from the x axis.
Homework Equations
ψ{x,y,z,t) = Aei(kx+ky+kz ± ωt)
k = 2π/λ
The Attempt at a Solution
im not finding many good examples on this but using the plug and chug method i came up with
ψ = Aei(.008(cosθ +sinθ) -ωt)
