Q32. A two-slit Young's experiment is done with monochromatic light of wavelength 6000 Å. Slits are 2 mm apart and fringes are observed on a screen placed 10 cm away from the slits. If a transparent plate of thickness 0.5 mm is placed in front of one of the slits, the interference pattern shifts by 5 mm. Then the refractive index of the transparent plate should be:Physics — Optics, Nature of Light and Optical Instruments — Question 32 of 155A. 1.1 B. 1.2 C. 1.3 D. 1.5Practice more Physics MCQs for entrance exam preparation on Examora.io.← Previous Question Next Question →
