If the free space between the plates is replaced by a transparent liquid of refractive index

1.5

and the wavelength of light remains

4200 \mathop A\limits^ \circ

the number of fringes seen will be:

View answer and explanation

Correct option: A

45

Option A (45) is correct because the number of fringes is directly proportional to the refractive index of the medium.
