Calculate Fringe Width







Formula

The formula to calculate the Fringe Width is:

\[ \beta = \frac{\lambda \cdot D}{d} \]

Where:

Definition

Fringe Width is the distance between two consecutive bright or dark fringes in an interference pattern, typically measured from the center of a bright fringe to the center of the next bright fringe.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \beta = \frac{0.268 \cdot 0.202}{0.106} \]

Evaluating:

\[ \beta = 0.510716981132076 \text{ m} \]

The Fringe Width is 0.510716981132076 m.
