In a Young's double slit experiment the separation between slits is `2 xx 10^(-3)m` whereas the distance of screen from the plane of slits is 2.5m. Light of wavelengths in the range 2000-8000 Å is allowed to fall on the slits. Find the wavelengths in the visible region that will be present on the screen at `10^(-3)` m from the central maxima.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify Given Values
We are given:
- Separation between slits, \( d = 2 \times 10^{-3} \, \text{m} \)
- Distance from the slits to the screen, \( D = 2.5 \, \text{m} \)
- Distance from the central maxima to the point on the screen, \( y = 10^{-3} \, \text{m} \)
- Wavelength range: \( 2000 \, \text{Å} \) to \( 8000 \, \text{Å} \)
