Q44. 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 5x10-2m towards the slits, the change in fringe width is 3x10-5 m. If the separation between the slits is 10-3 m, the wavelength of light used is:Physics — Optics, Nature of Light and Optical Instruments — Question 44 of 155A. 6000 Å B. 5000 Å C. 3000 Å D. 4500 Å Practice more Physics MCQs for entrance exam preparation on Examora.io.← Previous Question Next Question →
