Question

Snell's law of refraction of light states that

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Snell's law states that the ratio of the sine of the angle of incidence to the sine of angle of refraction is a constant for any two media for the same colour or wavelength of light. The constant is called the refractive index and is generally denoted by µ or n.

μ = sin i / sin r
