A planar electromagnetic wave is propagating in the +x direction. At a certain point P and at a giveninstant, the electric field of the wave is given by = (0.082 V/m) . What is the Poynting vector at thepoint P at that instant? (c = 3.0 x 10^8 m/s, ?
Plane - polarized light is incident on a single polarizing disk, with the direction of E 0 parallel to the direction of the transmission axis. Through what angle should the disk be rotated so that the intensity in the transmitted beam is reduced by a factor of (a) 2.00, (b) 4.00, and (c) 6.00?
An incident wave along (1/2) i - (√3/2)j falls on a refractive surface at z = 0. If the refractive index is μ= √3 , find the propagation vectors for the reflected and the refracted rays.
