# Problem: A microwave oven operates at 2.4 GHz with an intensity inside the oven of 2700W/m2 .(A) What is the amplitude of the oscillating electric field?(B) What is the amplitude of the oscillating magnetic field?

###### FREE Expert Solution

(A)

The amplitude of oscillating electric field:

$\overline{){{\mathbf{E}}}_{{\mathbf{0}}}{\mathbf{=}}\sqrt{\mathbf{2}{\mathbf{\mu }}_{\mathbf{0}}\mathbf{Ic}}}$

E0 = (2µ0Ic)(1/2)

To determine the amplitude of the electric field, we are going to substitute the values of µ0, I and c.
