Problem

In YDSE the separation between slits is

2 \times 10^{-3} \text{ m}

whereas the distance of screen from the plane of slits is

2.5 \text{ m}

. A light of wavelengths in the range

2000 - 8000 \text{ \AA}

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

10^{-3} \text{ m}

from the central maxima will be (a)

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

(b)

2000 \text{ \AA}, 4000 \text{ \AA}

(c)

3000 \text{ \AA}, 6000 \text{ \AA}

(d)

4000 \text{ \AA}, 8000 \text{ \AA}
