PYQ In Young's double-slit experiment, if the separation between coherent sources is halved and the distance of the screen from the coherent sources is doubled, then the fringe width becomes: 1. half 2. four times 3. one-fourth 4. double Ruhul Amin Alig
PMQ In Young’s double slit experiment, the slits are 2 mm apart and are illuminated by photons of two wavelengths l1 = 12000 Å and l2 = 10000 Å. At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other? (a) 4 mm (c) 8 mm (b) 3 mm (d) 6 mm Ruhul Amin Alig
Easy MCQs Physics In Young's double slit experiment, fringes of width β are produced on the screen kept at a distance of 1m from the slit. When the screen is moved away by 5×10 −2 m, fringe width changes by 3×10 −5 m. The separation between the slits is 1×10 −3 m. The wavelength of light used is __________nm. Ruhul Amin Alig
