In a two slit experiment with monochromatic light fringes are obtained on a screen placed at some distance from the slits. If the screen is moved by \(5 \times 10^{-2} \mathrm{~m}\) towards the slits, the change in fringe width is 3 × 10–5 m. If separation between the slits is 10–3 m, the wavelength of light used is
- 6000 Å
- 5000 Å
- 3000 Å
- 4500 Å
Answer
(A) 6000 Å
