MCQ
In Young's double slit experiment, the phase difference between the light waves reaching third bright fringe from the central fringe will be ($\lambda$ $=6000 Å$ )
- AZero
- B$2\pi $
- C$4\pi $
- ✓$6\pi $
✓
Answer
Correct option: D.
$6\pi $
d
(d)$\because n = 3,\;\;\therefore 2n\pi = 2 \times 3\pi = 6\pi $
(d)$\because n = 3,\;\;\therefore 2n\pi = 2 \times 3\pi = 6\pi $
