Young's Double Slit Experiment (YDSE)

Young's Double Slit Experiment (YDSE)

### Fringe Width

$$\beta=\frac{\lambda D}{d}$$

### Terminologies

- β → Fringe width.

- λ → Wavelength of light.

- D → Distance between slit and screen.

- d → Separation between two slits.

### Conditions / Special Cases

Fringe width increases with:

$$\lambda\uparrow$$

$$D\uparrow$$

Fringe width decreases with:

$$d\uparrow$$

### Usage

- Used to calculate distance between consecutive brig
