A beam of light of wavelength 600 nm from a distance source falls on a single slit 1 mm wide and resulting diffraction pattern is observed on a screen 2m away. What is the distance between the first bright fringes on either side of the central bright fringe ?

Explanation

To solve the problem step by step, we will follow the principles of single-slit diffraction.

### Step 1: Understand the Given Data
We have the following data:
- Wavelength of light, \( \lambda = 600 \, \text{nm} = 600 \times 10^{-9} \, \text{m} \)
- Width of the slit, \( d = 1 \, \text{mm} = 1 \times 10^{-3} \, \text{m} \)
- Distance from the slit to the screen, \( D = 2 \, \text{m} \)
