Visible light of wavelength 
falls normally on a single slit and produces a diffraction pattern. It is found that the second diffraction minima is at 
from the central maxima. If the first minimum is produced at 
, then 
is close to
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For single slit diffraction experiment:
Angle of minima are given by
Dividing (1) and (2)
As, the value is coming less than 
the only available option are 
and 
but by using approximation we get
