MCQ
In Young's double slit interference experiment, the slit separation is made $3 $ fold. The fringe width becomes
- ✓$1/3$ times
- B$1/9$ times
- C$3 $ times
- D$9$ times
✓
Answer
Correct option: A.
$1/3$ times
a
(a)$\beta \propto \frac{1}{d}$==> If $d$ becomes thrice, then $\beta $ become becomes $\frac{1}{3}$ times.
