3 In a
Young’s slit experiment a coherent source of light of wavelength 600 nm is
used. The slits are 0.4mm apart and the screen is 1.2m from the sources. The
fringe separation is
A 1.8 x 10-3
mm
B 18 mm
C 1.8 x 10-3
m
D 18 cm (4

4. In the
pattern formed by a Young’s slit experiment the distance from the central
fringe to the 10th bright fringe is 3.44cm. If the screen is 2m form
the sources and λ = 0.589 µm the slit separation is
A 3.4 mm
B 2.9 mm
C 0.34 mm
D 0.74mm (4
