Question

The electric field of a plane electromagnetic wave in free space travelling along x -direction is given by : E z ​ = 60 sin ( k x + ω t ) V / m . The magnetic field component will be given as : Here c represents the speed of light in free space.

TestHub · Accepted Answer

Given E z ​ = 60 sin ( kx + ω t ) V / m . The magnetic field component must be perpendicular to E z ​ and x . Also B 0 ​ = c E 0 ​ ​ = c 60 ​ . Thus B y ​ = c 60 ​ sin ( kx + ω t ) .
