In Young's double slit experiment with wavelength 5890 `Å`, there are 60 fringe in the field of vision, How many fringes will be observed in the same field of vision id wavelength used is 5460 `Å`?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the relationship between the number of fringes and wavelength
In Young's double slit experiment, the number of fringes (N) observed in a given field of vision is directly proportional to the wavelength (λ). The relationship can be expressed as:
\[ N \propto \frac{1}{\lambda} \]
This means that if the wavelength decreases, the number of fringes increases, and vice versa.

### Step 2: Set up the equation for the two wavelengths
