Question

The brewster angle for air to water interface is sin-1

Answer 1

Answer:

Using Snell's law, one can calculate the incident angle θ1 = θB at which no light is reflected: For a glass medium (n2 ≈ 1.5) in air (n1 ≈ 1), Brewster's angle for visible light is approximately 56°, while for an air-water interface (n2 ≈ 1.33), it is approximately 53°.
