MCQ
The fringe width in Young’s double slit experiment increases when
- ✓Wavelength increases
- BDistance between the slits increases
- CDistance between the source and screen decreases
- DThe width of the slits increases
✓
Answer
Correct option: A.
Wavelength increases
a
(a)$\beta = \frac{{\lambda D}}{d} \Rightarrow \beta \propto \lambda $
(a)$\beta = \frac{{\lambda D}}{d} \Rightarrow \beta \propto \lambda $
