If in a Young's double slit experiment the slit separation is doubled and the distance of the screen from the slits is reduced to half, then the fringe widths become how many times their original value?
- A \(\frac{1}{2}\)
- B 2
- C \(\frac{1}{4}\)
- D 4
Answer & Solution
Correct Answer
(C) \(\frac{1}{4}\)
Step-by-step Solution
Detailed explanation
Fringe width in Young's double slit experiment is given as \(\beta=\frac{D \lambda}{d}\) where, \(D=\) distance between source and screen and \(\quad d=\) slit width.…
