If the refractive index for light going from air to diamond be 2.42, what will bethe refractive index for light going from diamond to air?

Explanation

To find the refractive index for light going from diamond to air, we can use the relationship between the refractive indices of two media. Here’s the step-by-step solution:

### Step 1: Understand the given information
We know that the refractive index of diamond with respect to air (n_diamond/air) is given as 2.42. This means that light travels slower in diamond than in air.

### Step 2: Use the formula for refractive indices
The refractive index of a medium A with respect to medium B can be expressed as:
\[ n_{A/B} = \frac{c}{v} \]
