Abeam of natural light is incident on an air-glass
interface(nti=1.5) at 40 degrees . compute the degree
ofpolarization of the reflected light.

The degree of polarization of the reflected light

Solution:

As per the question:

Refractive index,

Angle of incidence,

Now,

To calculate the degree of polarization:

We know according to the laws of reflection, angle of incidence and angle of reflection are equal.

Also, from Brewster law:

magnityde and direction

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
