The wavelength range of white light is 400 nm to 700 nm. What will be the wavelength range if light passes through water? Refractive index of water is 1.33.

Explanation

To find the wavelength range of white light when it passes through water, we can follow these steps:

### Step 1: Understand the relationship between wavelength, refractive index, and medium
When light travels from one medium to another, its wavelength changes according to the formula:
\[ \lambda' = \frac{\lambda}{\mu} \]
where:
