The Correct Option is B
Solution and Explanation
Step 1: Definition.
Refraction is bending of light when it passes from one medium to another.
Step 2: Laws.
1. Incident ray, refracted ray and normal lie in the same plane.
2. Snell’s law: $\dfrac{\sin i}{\sin r} = \mu$, a constant for given media.
Step 3: Conclusion.
Thus, there are 2 laws.
