When the amplitude electric field increase from e to 3e, the intensity of the wave will increase by a factor of 9.

Intensity and amplitude electric field

The relationship between intensity and amplitude of an electric field given as;

I ∝ E₀²

[tex]\frac{I_1}{E_1_0^2} = \frac{I_2}{E_2_0^2}\\\\I_2 = \frac{I_1E_2_0^2}{E_1_0^2}[/tex]

where;

  • I is the intensity of the wave
  • E is the amplitude electric field

When the  amplitude electric field increase from e to 3e

[tex]I_2 = \frac{I_1 \times (3e)^2}{(e)^2} \\\\I_2 = 9I_1[/tex]

Thus, when the amplitude electric field increase from e to 3e, the intensity of the wave will increase by a factor of 9.
