Calculate the electric field and magnetic field produced by the rediation coming from a 100 W bulb at a distance of 3 m. Assume that the efficiency of the bulb is 2.5 % and it is a point source.

Electromagnetic waves are those waves in which these are sinusoidal variation of electric and magnetic fields at right angle to each other as well as right angle ot the direction of propagation. The ratio of electric vector and magnetic vector gives the velocity of light and vecExxvecB gives the direction of propagation of electromagnetic wave. The electric field intensity produced by the radiations coming from 100 W bulb at a 3 m distance of E. The electric field intensity produced by the radiations coming from the 50 W bulb at the same distance is
