प्रश्न

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.
