Question

g Suppose the intensity of some electromagnetic wave doubles. What happens to the amplitude of the wave's electric field?

Answer 1

The amplitude of the wave's electric field is  $\sqrt{2}$ times if the intensity of some electromagnetic wave doubles.

• What is electromagnetic wave:

Electromagnetic waves also called EM waves, are waves that are created as a result of vibrations between an electric field and magnetic field.

The formula of Intensity of electromagnetic wave:

• I = 1/2 ( c* ε(0)* E(0)^2 )

where c is speed of light

E is amplitude of electric field

here Intensity of EM waves doubles so,

I' = 2*I

we can say that,

I ∝ E^2

E = sqrt ( I )

E' = sqrt ( 2*I )

hence

E' = $\sqrt{2}$ * E

so, the amplitude of the wave's electric field is  $\sqrt{2}$ times if the intensity of some electromagnetic wave doubles
