The optical path of a monochromatic light is the same if it goes through 2.00 cm of glass or 2.25 cm of water. If the refractive index of water is 1.33, what is the refractive index of glass?

Explanation

To solve the problem, we need to use the concept of optical path length. The optical path length (OPL) is given by the product of the refractive index (n) of the medium and the physical length (d) of the medium through which light travels.

### Step-by-Step Solution:

1. **Identify Given Values**:
- Distance traveled in glass (d_g) = 2.00 cm
- Distance traveled in water (d_w) = 2.25 cm
- Refractive index of water (n_w) = 1.33
