Problem Statement

What is Snell's law?

Step-by-Step Explanation

Snell's law relates the angles and refractive indices when light passes between media.

  1. Identify what the question is asking. In Waves and Optics, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Key Formula

n1sin⁡θ1=n2sin⁡θ2n_1\sin\theta_1=n_2\sin\theta_2

Final Answer

Snell's law relates the angles and refractive indices when light passes between media. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
