A sinusoidal electromagnetic wave is propagating in vacuum. At a given point P and at a particular time, the electric field is in the +x direction and the magnetic field is in the -y direction
(a) What is the direction of propagation of the wave? (b) If the intensity of the wave at point P is 0.36 W/m2, what is the electric field amplitude at that point? (c = 3.00 × 108 m/s, ?0 = 4? × 10-7 T • m/A, ?0 = 8.85 × 10-12 C2/N • m2)
