Light of wavelength 600 nm falls from a distant source on a slit 0.6 mm wide. Find the distance between the two dark bands, on either side of the central bright band of the diffraction pattern observed , on a screen placed 2 m from the slit.

Explanation

To solve the problem, we need to find the distance between the two dark bands on either side of the central bright band in a diffraction pattern created by a single slit.

### Step-by-Step Solution:

**Step 1: Identify the given values.**
- Wavelength of light, \( \lambda = 600 \, \text{nm} = 600 \times 10^{-9} \, \text{m} \)
- Width of the slit, \( d = 0.6 \, \text{mm} = 0.6 \times 10^{-3} \, \text{m} \)
- Distance from the slit to the screen, \( D = 2 \, \text{m} \)
