The refractive index of glass with respect to air is 1.5. What is the value of the refractive index of air with respect to glass?

Explanation

To find the refractive index of air with respect to glass, 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 glass with respect to air (n_glass/air) is given as 1.5. This can be expressed mathematically as:
\[ n_{glass/air} = 1.5 \]

### Step 2: Use the formula for refractive indices
The refractive index of one medium with respect to another can be expressed as:
