Question

In an electromagnetic wave propagating along with magnetic field of frequency of 3 into 10 raise to minus 10

Answer 1

Explanation:

The time average of the energy flux is the intensity I of the electromagnetic wave and is the power per unit area. It can be expressed by averaging the cosine function in Equation over one complete cycle, which is the same as time-averaging over many cycles (here, T is one period):

Answer 2

Answer -

• In an electromagnetic wave propagating along X direction, the magnetic field oscillates at a frequency of 3*10^10 Hz and has an amplitute of 10^-7 Tesla acting along the Y-axis.
