Describe the method of obtaining plane polarized light by the method of reflection and deduce the brewster law? 50 points...plz answer ... in good way..6 marks​

Answer 1

Answer:

This law is named after Sir David Brewster, a Scottish physicist, who proposed the law in the year 1811. The law states that the p-polarized rays vanish completely on different glasses at a particular angle. ... While, the unpolarized light at this angle is transmitted, the light is reflected from the surface.

Answer 2

Brewster's law, relationship for light waves stating that the maximum polarization (vibration in one plane only) of a ray of light may be achieved by letting the ray fall on a surface of a transparent medium in such a way that the refracted ray makes an angle of 90° with the reflected ray.

Using θB to represent Brewster's angle, the equation for Brewster's formula is: θB = arctan(n2/n1). Here's a breakdown of what this means. In our formula, θB represents the angle we're trying to calculate (Brewster's angle). ... Placing them in the formula, you get θB = arctan(1.33/1.00) or θB = arctan(1.33).
