Show graphically the intensity distribution in Fraunhofer.s single slit diffraction experiment. Label the axes.

Explanation

To graphically represent the intensity distribution in Fraunhofer's single slit diffraction experiment, we will follow these steps:

### Step 1: Understand the Setup
In a Fraunhofer single slit diffraction experiment, a monochromatic light wave passes through a single slit of width 'a'. The light diffracts and creates a pattern of intensity on a screen placed far away from the slit.

### Step 2: Define the Axes
- **X-axis**: This will represent the angle θ (in radians) or the position on the screen (y) relative to the center of the central maximum.
- **Y-axis**: This will represent the intensity (I) of the light, which varies with the angle or position.
