  • Question 1/10
    4 / -1
    In Young\'s double slit experiment, carried out with light of wavelength λ = 5000 Å, the distance between the slits is 0.2 mm and the screen is at 200 cm from the slits. The central maximum is at x = 0. The third maximum (taking the central maximum as zeroth maximum) will be at x equal to
    Solutions

  • Question 2/10
    4 / -1
    In a Young\'s experiment, two coherent sources are placed 0.90 mm apart and the fringes are observed one metre away. If it produces the second dark fringe at a distance of 1 mm from the central fringe, the wavelength of monochromatic light used would be
    Solutions

  • Question 3/10
    4 / -1
    In Young\'s double slit experiment, the distance between the two slits is 0.1 mm and the wavelength of light used is 4 × 10–7 m. If the width of the fringe on the screen is 4mm, the distance between screen and slit is
    Solutions

  • Question 4/10
    4 / -1
    In Young\'s double slit experiment, the distance between sources is 1mm and distance between the screen and source is 1 m. If the fringe width on the screen is 0.06 cm, then λ =
    Solutions

  • Question 5/10
    4 / -1
    If a torch is used in place of monochromatic light in Young\'s experiment what will happen?
  • Question 6/10
    4 / -1
    When a thin metal plate is placed in the path of one of the interfering beams of light
  • Question 7/10
    4 / -1
    In Young\'s experiment, the distance between slits is 0.28 mm and distance between slits and screen is 1.4 m. Distance between central bright fringe and third bright fringe is 0.9 cm. What is the wavelength of used light?
    Solutions

  • Question 8/10
    4 / -1
    Two parallel slits 0.6 mm apart are illuminated by light source of wavelength 6000 Å. The distance between two consecutive dark fringes on a screen lm away from the slits is
    Solutions

  • Question 9/10
    4 / -1
    A narrow slit of width 2 mm is illuminated by monochromatic light of wavelength 500 nm. The distance between the first minima on either side on a screen at a distance of lm is
    Solutions

  • Question 10/10
    4 / -1
    If a transparent medium of refractive index µ = 1.5 and thickness t = 2.5 × 10–5 m is inserted in front one of the slits of Young\'s Double Slit experiment, how much will be the shift in the interference pattern? The distance between the slit is 0.5 mm and that between slits and screen is 100 cm
