A Sinusoidal Electromagnetic Wave Is Propagating in Vacuum

question 17

Short Answer

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,μ₀ = 4π × 10^-7 T • m/A,ε₀ = 8.85 × 10^-12 C²/N • m²)
