Assignment

1. Calculate the angle of incidence of a laser red light at which the reflected light is plane polarised. Let us consider a material of crown glass in a medium of Helium.
2. Calculate the Brewster's angle for green light incident on a topaz surface when the angle of the polariser is 155 degrees.
3. A blue light is incident on a flint glass in a medium of air. If the angle of the polariser is 205 degrees, calculate the Brewster's angle.
4. Using laser green light, study the variation of Brewster's angle for different materials of different refractive index with air as the medium.
5. A laser blue light is falling on a topaz surface. Obtain the change in Brewster's angle with different media.
