  • Question 1/10
    4 / -1
    In an interference experiment, the spacing between successive maxima or minima is
    Solutions

  • Question 2/10
    4 / -1
    In Young's double slit experiment, slit separation is 0.6 mm and the separation between slit and screen is 1.2 m. The angular width is (the wavelength of light used is 4800A°).
    Solutions

  • Question 3/10
    4 / -1
    Colours in thin films are due to
  • Question 4/10
    4 / -1
    In a double slit experiment, the distance between slits is increased 10 times whereas, their distance from screen is halved, then what is the fringe width?
  • Question 5/10
    4 / -1
    To demonstrate the phenomenon of interference we require two sources, which emits radiations of
  • Question 6/10
    4 / -1
    On introducing a thin film in the path of one of the two interfering beams, the central fringe will shift by one fringe width. If μ =1.5, the thickness of the film is (wavelength of monochromatic light is λ)
    Solutions

  • Question 7/10
    4 / -1
    The maximum number of possible interference maxima for slit separation equal to twice the wavelength is Young's double-slit experiment, is
    Solutions

  • Question 8/10
    4 / -1
    The ratio of maximum and minimum intensities of two sources is 4 : 1. The ratio of their amplitudes is
  • Question 9/10
    4 / -1
    A beam of light of wavelength 600 nm from a distant source falls on a single slit 1 mm wide and the resulting diffraction pattern is observed on a screen 2 m away. The distance between the first dark fringes on either side of the central bright fringe is
    Solutions

  • Question 10/10
    4 / -1
    If white light is used in the Newton's rings experiment, the colour observed in the reflected light is complementary to that observed in the transmitted light through the same point. This is due to
