Draw a graph showing the intensity distribution of fringes due to diffraction at single slit

Explanation

To draw the graph showing the intensity distribution of fringes due to diffraction at a single slit, follow these steps:

### Step 1: Set Up the Axes
- Draw a horizontal line for the x-axis and label it as "Diffraction Angle (θ)".
- Draw a vertical line for the y-axis and label it as "Intensity (I)".

### Step 2: Mark the Central Maximum
- At θ = 0 (the center of the graph), mark the highest point on the y-axis. This represents the central maximum, where the intensity is at its peak. Label this point as "I_max".
