A beam of polarized light with an average intensity of 14.5 W/m² is sent through a polarizer. The transmission axis makes an angle of 25.0° with respect to the direction of polarization. Determine the rms value of the magnetic field of the transmitted beam.

Explanation:

Intensity, Io = 14.5 W/m²

θ = 25°

By the law of Malus

I = 11.91 W/m²

Now the formula for the rms value of magnetic field is given by

Brms = 2.23 x 10^-7 tesla

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt
