Electromagnetic Waves as Sinusoidal Waves Video Lessons

Concept

# Problem: An electromagnetic wave propagates through a vacuum in the +x-direction, carrying an intensity of 150 W/m2. At t = 0, the electric field has zero amplitude, and after 0.01 s, the electric field strength grows to its maximum value, pointing in the +y direction. Write equations describing the electric and magnetic fields as sinusoidal oscillations, including the appropriate unit vectors to denote direction.
