The two slits are 1mn apart from each of ther and illuminated with a light of wavelength 
If the distance of the screen is 1m from the slites, then the distance between third dark frings and fifth bright frings is:
Text Solution
Verified by ExpertsThe correct answer is:
C
: Given : 
Distance of 
bright fringes from the centre 
Where n = 1,2,3……
So the distance of 
bright fringes 
Distance of 
dark fringe from the centre
Where n= 1,2,3……
dark fringe 
Distance between them
