White light is a mixture of light of wavelengths between 400 nm and 700 nm. If this light goes through water `(mu = `1.33)` what are the limits of the wavelength there ?

Explanation

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

### Step 1: Understand the relationship between wavelength, refractive index, and medium
The refractive index (μ) of a medium can be defined as the ratio of the speed of light in vacuum (or air) to the speed of light in the medium. Mathematically, this is expressed as:
\[ \mu = \frac{c}{v} \]
where \( c \) is the speed of light in vacuum and \( v \) is the speed of light in the medium.

### Step 2: Use the relationship between wavelength and refractive index
