In the Young's double slit experiment, when a monochromatic light is used, fringe width obtained is 1 mm . If the wave length is halved and the slit width is doubled, what will be the new fringe width?
- A 1 mm
- B 0.25 mm
- C 1.25 mm
- D 0.5 mm
Answer & Solution
Correct Answer
(B) 0.25 mm
Step-by-step Solution
Detailed explanation
The fringe width \(\beta\) in Young's double slit experiment is given by the formula \(\beta = \dfrac{\lambda D}{d}\), where \(\lambda\) is the wavelength of light, \(D\) is the distance between the slits and the screen, and \(d\) is the distance between the two slits. Given the…
