When monochromatic light of wavelength is used in Young's double slit experiment, the fifth order bright fringe is formed at from the central bright fringe on the screen. If the experiment is conducted with light of wavelength from the central bright fringe, the third order bright fringe will be located at
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
In Young's double slit experiment, fringe width is given by β=λDd. Therefore, fringe width is proportional to the wavelength of the light used. Now fringe width in the first case is β1=65=1.2 mm. Therefore,…
