The Y-Component of the Electric Field of an Electromagnetic Wave

question 11

Short Answer

The y-component of the electric field of an electromagnetic wave traveling in the +x direction through vacuum obeys the equation Ey = (375 N/C) cos[kx - (2.20 × 10¹⁴ rad/s)t]. (c = 3.0 x 10⁸ m/s)
(a) What is the largest that the x-component of the wave can be?
(b) What is the largest that the z-component of the wave can be?
