Academics

A plane sinusoidal electromagnetic wave has a magnetic field amplitude of 5.00 x 10^-5 T.

a) What is the electric field amplitude of the wave?

b) How much energy is contained in a volume of 1.0 x iOm3,if the wave completely fills this volume?

c) What average force does this radiation exert on a totally reflecting surface of area0.500 m2, if the plane of the surface is perpendicular to the direction of propagation of the wave?
