In Young's double slit experiment, white light is used. The seperation between the slits is kept `1 mm` and intensity is observed on screen distance `2m` from the plane of the slits. At a point on the screen directly opposite to the either slit which of the following wavelength is not present

Options

A. ultraviolet
B. red
C. Yellow
D. violet

Explanation

To solve the problem, we need to determine which wavelength of light is not present at a point on the screen directly opposite either of the slits in Young's double slit experiment when white light is used.

### Step-by-Step Solution:

1. **Understand the Setup**:
- We have a double slit experiment with a slit separation \( d = 1 \, \text{mm} = 1 \times 10^{-3} \, \text{m} \).
- The distance from the slits to the screen is \( D = 2 \, \text{m} \).
- We are looking for the wavelength of light that produces a minimum at the point directly opposite one of the slits.
