In Young's double slit experiment, how many maxima can be obtained on a screen (including central maxima), if 
(where 
is the wavelength of light)?
Text Solution
Verified by ExpertsThe correct answer is:
A
5
In YDSE, path difference, 
For maxima, 
, where n = 0, ±1, ±2....
(given that 
)
......... (i)
Since, 
Form (i) 
So, 
So, possible values of n are -2, -1, 0, 1,2. Thus a total of 5 maxima will be obtained.
