How does the angular separation between fringes in single-slit diffraction experiment change when the distance of separation between the slit screens is doubled?

उत्तर
We know angular separation is given as
`theta = beta/D = (Dlambda)/(d/D) =lambda/d`
Since θ is independent of D, the distance of separation between the screen and the slit so when D is doubled, angular separation would remain same.

A long narrow horizontal slit is paced 1 mm above a horizontal plane mirror. The interference between the light coming directly from the slit and that after reflection is seen on a screen 1.0 m away from the slit.
