Problem

In YDSE, the separation between the slits is

2\times10^{-3}\text{ m}

, whereas the distance of the screen from the plane of the slits is

2.5\text{ m}

. Light of wavelengths in the range

2000

8000\text{ Å}

is allowed to fall on the slits. The wavelengths in the visible region that will be present on the screen at

10^{-3}\text{ m}

from the central maximum will be (a)

\frac{8000}{3}\text{ Å},\ 2000\text{ Å}

(b)

2000\text{ Å},\ 4000\text{ Å}

(c)

3000\text{ Å},\ 6000\text{ Å}

(d)

4000\text{ Å},\ 8000\text{ Å}
