14. Light with a wavelength of 646 nm passes through two slits and forms an interference pattern on a screen 8.75 m away. The distance between the central bright fringe and the second-order bright fringe is 5.16 cm. What will be the distance between the central bright fringe and the third-order minimum! A) 0.13 m B) 0.18 m C) 0.24 m D) 0.34 m E) 0.47 m

EXPERT ANSWER According to question, light has wavelength,  = 646 nm = 646 * 10-9 m. distance of screen from slits, D = 8.75 m Distance between central bright fringe and second order bright fringe is, y = 5.16 cm = 5.16 * 10-2 m. i.e for n = 2 Since, for maxima Where d is distance between …
