2 Light of wavelength 5000 is incident on a slit of width 2 mm in Fraunhoffer diffraction Find the width of second maximum on the screen placed at the focal plane of the convex lens of a focal length 100 cm The lens is placed close to the slit Ans 0 025 cm 3 An apparatus for Young s experiment is immersed in a liquid of refractive index 1 33 The distance between two slits is 1 mm and that between slits and screen is 1 33 m The wavelength of light used is 6300 in air 1 Find the distance between two consecutive bright fringes 2 Keeping the apparatus in the liquid one of the slits is covered with a glass plate of refractive index 1 53 If in
