The two slits are

1\,mm

apart from each other and illuminated with a light of wavelength

5 \times {10^{ - 7}}\,m

. If the distance of the screen is

1\,m

from the slits, then the distance between third dark fringe and fifth bright fringe is

View answer and explanation

Correct option: C

1.25\,mm

Option C (

1.25\,mm

) is correct because it's the calculated difference between the positions of the 5th bright and 3rd dark fringes in the interference pattern.
