If wavelength of light in glass is 7200`overset(o)(A)`, then find the wavelength of same light (in `overset(o)(A)`)in water `(mu_w=4//3, mu_(g)=3//2)`

Explanation

To find the wavelength of light in water given its wavelength in glass, we can use the relationship between wavelength and refractive index. The wavelength of light in different media is inversely proportional to the refractive index of those media.

### Step-by-Step Solution:

1. **Identify Given Values:**
- Wavelength in glass, \( \lambda_g = 7200 \, \text{Å} \)
- Refractive index of glass, \( \mu_g = \frac{3}{2} \)
- Refractive index of water, \( \mu_w = \frac{4}{3} \)
