If one of the slits in Young's experiment is covered, what effect will be intensity of light at the centre of the screen?

Explanation

To solve the problem of how the intensity of light at the center of the screen is affected when one of the slits in Young's double slit experiment is covered, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Initial Setup**:
In Young's double slit experiment, we have two slits (let's call them Slit 1 and Slit 2) that act as coherent light sources. When both slits are open, they produce an interference pattern on the screen, with a central bright fringe (central maxima) at the center.

**Hint**: Remember that the central maxima occurs where the path difference between the light from the two slits is zero.
