  • Question 1/10
    4 / -1
    A polarizer is used to
  • Question 2/10
    4 / -1
    Through which character we can distinguish the light waves from sound waves
  • Question 3/10
    4 / -1
    The angle of polarisation for any medium is 60°, what will be critical angle for this?
    Solutions

  • Question 4/10
    4 / -1
    The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index n) is
    Solutions

  • Question 5/10
    4 / -1
    A polaroid is placed at 45° to an incoming light of intensity I0 . Now the intensity of light passing through polaroid after polarisation would be
    Solutions

  • Question 6/10
    4 / -1
    Plane polarised light is passed through a polaroid. On viewing through the polaroid we find that when the polaroid is given one complete rotation about the direction of the light, one of the following is observed
  • Question 7/10
    4 / -1
    Out of the following statements which is not correct?
  • Question 8/10
    4 / -1
    A ray of light is incident on the surface of a glass plate at an angle of incidence equal to Brewster\'s angle ϕ. If µ represents the refractive index of glass with respect to air, then the angle between reflected and refracted rays is
  • Question 9/10
    4 / -1
    Figure represents a glass plate vertically on a horizontal table with a beam of unpolarised light falling on its surface at the polarising angle of 57° with the normal. The electric vector in the reflected light on screen S will vibrate with respect to the plane of incidence in a

    Solutions

  • Question 10/10
    4 / -1
    A beam of light AO is incident on a glass slab (µ = 1.54) in a direction as shown in figure. The reflected ray OB is passed through a Nicol prism. On viewing through a Nicole prism, we find on rotating the prism that
