When reflection occurs from denser to………….., then `(mu_(2))/(mu_(1)) = ………` .

Explanation

To solve the question, we need to analyze the relationship between the refractive indices of two media when reflection occurs from a denser medium to a rarer medium.

### Step-by-Step Solution:

1. **Understanding the Context**:
- We are dealing with two media: a denser medium (medium 1) and a rarer medium (medium 2).
- When light travels from a denser medium to a rarer medium, we need to apply Snell's law.
