Question 14 The electric field of an electromagnetic wave traveling in vacuum is described by the wave function Ey = (375 V/m) cos[kx - (3.20 x 10 # rad/s)t], where k is the wave number in rad/m, x is in m, t is in s. Find the wavelength in micrometers (um) of this wave. DIL F6 F3 F4 esc X F1 F2 LA @ 6 UT 3 4 2 R W EMoving to another question will save this response.
