  • Question 1/10
    4 / -1
    A single slit is used to observe diffraction pattern with red light. On replacing the red light with violet light the diffraction pattern would
  • Question 2/10
    4 / -1
    A beam of light wavelength 600 nm from a source falls on 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
  • Question 3/10
    4 / -1
    In single slit experiment, the width of the slit is reduced. Then, the linear width of the principal maxima
  • Question 4/10
    4 / -1
    A grating which would be most suitable for constructing a spectrometer for the visible and ultraviolet region, should have
  • Question 5/10
    4 / -1
    In single slit diffraction pattern
  • Question 6/10
    4 / -1
    A parallel monochromatic beam of light is incident normally on a narrow slit. A diffraction pattern is formed on a screen placed perpendicular to the direction of incident beam. At the first maximum of the diffraction pattern, the phase difference between the rays coming from the edges of the slit is
  • Question 7/10
    4 / -1
    Two luminous point sources separated by a certain distance are at 10 km from an observer. If the aperture of his eye is 2.5 × 10-3 m and the wavelength of light used is 500 nm, the distance of separation between the point sources just seen to be resolved is
    Solutions

  • Question 8/10
    4 / -1
    Maximum diffraction takes place in a given slit for
  • Question 9/10
    4 / -1
    In the phenomenon of diffraction of light, when blue light is used in the experiment instead of red light, then
  • Question 10/10
    4 / -1
    The size of an obstacle in order to observe diffraction of light must be
