Correct option is A- It becomes four times larger-The intensity of the wave is proportional to the square of the amplitude- so it becomes four times larger-

Assume the amplitude of the electric field in a plane electromagnetic wave is $$E_1$$ and the amplitude of the magnetic field is $$B_1$$. The source of the wave is then adjusted so that the amplitude of the electric field doubles to become $$2E_1$$. What happens to the intensity of the wave?

Correct option is A. It becomes four times larger.
The intensity of the wave is proportional to the square of the amplitude. so it becomes four times larger.
