He-Ne lasers are often used in physics demonstrations. They produce light of wavelength 633 nm and a power of 0.700 mW spread over a cylindrical beam 1.20 mm in diameter (although these quantities can vary).

1) What is the intensity of this laser beam?

2) What is the maximum value of the electric field?

3) What is the maximum value of the magnetic field?

4) What is the average energy density in the laser beam?
