and magnetic field of radiation?

2. Assuming that all the energy from a 1000 W lamp is radiated uniformly, calculate the average

value of the intensity of electric field of radiation at a distance of 2 m from the lamp.

3. If the magnitude of electric field vector in a plane wave is 377 V/m, determine the magnitude

of magnetic field vector for a plane wave in free space.
