Question

Q6. A monochromatic light of
wavelength 5100 Â from a narrow
slit is incident on a double slit. If
the overall separation of 10 fringes
on a screen 200 cm away is 2 cm
then, the separation between the
slit is​

Answer 1

Answer:

A monochromatic light of wavelength 5100 Å from a narrow slits is incident on a Young's double-slit in an experiment. The overall separation of 10 fringes on a screen in 2 cm. If the screen is 200 cm away, calculate the slit separation. ⇒d=Dλβ=2×5100×10-100.2=5.1×10-6m

Answer 2

A monochromatic light of

wavelength 5100 Â from a narrow

slit is incident on a double slit. If

the overall separation of 30 fringes

on a screen 200 cm away is 3 cm

then, the separation between the

slit is
