In case of diffraction from a singel slit, if red light is replaced by a blue light, what will be the effect on the fringe width?

Explanation

To determine the effect on the fringe width when red light is replaced by blue light in the case of diffraction from a single slit, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fringe Width Formula**:
The fringe width (β) in a single slit diffraction pattern is given by the formula:
\[
\beta = \frac{2\lambda D}{b}
