In a two slit experiment with monochromatic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by 5 × 10–2 m towards the slits, the change in fringe width is 3 × 10–5 m. If the distance between slits is 10–3 m, the wavelength of light will be
- 3000 Å
- 4000 Å
- 6000 Å
- 7000 Å
Answer
(C) 6000 Å
