283172 Distance of \(5^{\text {th }}\) dark fringe from centre is \(4 \mathrm{~mm}\). If \(D=2 \mathrm{~m}, \lambda=600 \mathrm{~nm}\), then distance between slits is:

1 \(1.35 \mathrm{~mm}\)
2 \(2.00 \mathrm{~mm}\)
3 \(3.25 \mathrm{~mm}\)
4 \(10.35 \mathrm{~mm}\)

283173 Assertion : Distance between position of bright and dark fringe remain same in YDSE.
Reason: Fringe width \(\beta=\frac{\lambda D}{d}\).

1 If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
3 If Assertion is correct Reason is incorrect.
4 If both the Assertion and Reason are incorrect.

283174 A light of wavelength \(500 \mathrm{~nm}\) is incident on a young's double slit. The distance between slits and screen is \(D=1.8 \mathrm{~m}\) and distance between slits is \(d=0.4 \mathbf{~ m m}\). If screen moves with a speed \(4 \mathrm{~m} / \mathrm{s}\), with what speed first maxima will move?

1 \(5 \mathrm{~mm} / \mathrm{s}\)
