3. Brewster's law in terms of refractive index can be Expressed​

Answer 1

Answer:

Brewster's law also states that the tangent of the angle of polarization, p, for a wavelength of light passing from one substance to another is equal to the ratio of the refractive indices, n1 and n2, of the two contacting mediums: tan p = n2/n1.

Answer 2

Brewster's law

Explanation:

• Brewster's law describes the relationship between light waves.
• It states that maximum polarization of a ray of light may be achieved by allowing the rap fall on the surface of a transparent medium.
• It should fall in such a way that the refracted ray makes an angle of 90° with the reflected ray.
• Thus when an unpolarised light falls on an interface, the reflected light is completely polarized if the angle of incidence is a specific angle called Brewster's angle.
• This angle is named after Sir David Brewster.
