In Young's double slit experiment, how many maxima’s can be obtained on a screen (including the central maximum) on both sides of the central fringes, if 
and 
?
Text Solution
Verified by ExpertsThe correct answer is:
B
For maximum (brightness) intensity on the screen, path difference should be integer multiple of wavelength, i.e.,
As, 
So, number of maximas 
Thus, only seven maximas can be obtained on both sides of the screen.
