Answer:
0.776 m far Pinhole should be placed before the viewing screen
Explanation:
For circular aperture of diameter D will have a bright central maximum of diameter, width is given by
where is wavelength of helium neon laser = 633 nm, D=10.cm, w=0.12 mm
Pinhole should be placed before the viewing screen is
Explanation:
It is given that,
Wavelength of monochromatic light,
Slits separation,
(a) We need to find the angle corresponding to the first bright fringe. For bright fringe the equation is given as :
, n = 1
(b) We need to find the angle corresponding to the second dark fringe, n = 1
So,
Hence, this is the required solution.
