  • Question 1/10
    4 / -1
    In a Young\'s double slit experiment, the slit separation is 0.2 cm, the distance between the screen and slit is lm. Wavelength of the light used is 5000 Å. The distance between two consecutive dark fringes (in mm) is
    Solutions

  • Question 2/10
    4 / -1
    In Young\'s double slit experiment, a minimum is obtained when the phase difference of super imposing waves is
  • Question 3/10
    4 / -1
    In Young\'s double slit experiment, the aperture screen distance is 2 m. The fringe width is 1 mm. Light of 600 nm is used. If a thin plate of glass (µ = 1.5) of thickness 0.06 mm is placed over one of the slits, then there will be a lateral displacement of the fringes by
    Solutions

  • Question 4/10
    4 / -1
    If Fresnel\'s biprism experiment is held in water instead of air, then what will be the effect on fringe width?
    Solutions

  • Question 5/10
    4 / -1
    What is the effect on Fresnel\'s biprism experiment when the use of white light is made?
  • Question 6/10
    4 / -1
    In Young\'s double slit experiment, the separation between the slit and the screen increases. The fringe width
    Solutions

  • Question 7/10
    4 / -1
    Young\'s double slit experiment is carrier out by using green, red and blue light, one colour at a time. The fringe widths recorded are βG, βR and βB, respectively. Then
    Solutions

  • Question 8/10
    4 / -1
    In Young\'s double slit experiment, one of the slit is wider than other, so that amplitude of the light from one slit is double of that from other slit. If Im be the maximum intensity, the resultant intensity I when they interfere at phase difference ϕ is given by
    Solutions

  • Question 9/10
    4 / -1
    Assuming that universe is expanding, if the spectrum of light coming from a star which is going away from earth is tested, then in the wavelength of light
  • Question 10/10
    4 / -1
    Doppler\'s effect in sound in addition to relative velocity between source and observer, also depends while source and observer or both are moving. Doppler effect in light depends only on the relative velocity of source and observer. The reason of this is
