Explanation:
It is given that,
The distance between the first spot and the central minimum is, s = 0.007 cm
Length, l = 12 m
Wavelength,
We need to find the width of the hair. Using the condition of diffraction pattern as :
, d is the width of the hair
d = 0.00102
or
So, the width of the hair is . Hence, this is the required solution.
