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

Solution

Angular separation is given by,
$straight theta space equals space straight beta over straight D space equals space fraction numerator Dλ divided by straight d over denominator straight D end fraction equals straight lambda over straight d$

Angular separation would remain same when the distance of separation between the slit and the screen is doubled.

Let us list some of the factors which could possibly influence the speed of wave propagation:
(i) nature of source.
(ii) direction of propagation.
(iii) motion of source and/or observer.
(iv) wave length.
(v) intensity of the wave.
On which of these factors, if any, does
(a) the speed of light in vacuum,
(b) the speed of light in a medium (say, the glass or water) depend?
