Multiple choice

The ratio of sine of the angle of incidence to the sine of the angle of refraction for a particular pair of media is constant. This ratio is known as

  1. Ohm's law

  2. Newton's Law

  3. Snell's Law

  4. None of these

C Correct answer
Explanation

Snell's Law defines the relationship between the angles of incidence and refraction for light passing through two different media. It states that the ratio of the sines of these angles is equal to the ratio of the refractive indices of the media.
