  • Question 1/10
    4 / -1
    H-polaroid is prepared by
  • Question 2/10
    4 / -1
    When unpolarised light beam is incident from air onto glass (n =1.5) at the polarising angle
  • Question 3/10
    4 / -1
    The correct curve between the energy of photon (E) and its wavelength (λ) in Fig. is
    Solutions

  • Question 4/10
    4 / -1
    In Young’s expt, the distance between two slits is d/3 and the distance between the screen and the slits is 3 D. The number of fringes in 1/3m on the screen, formed by monochromatic light of wavelength 3 λ, will be
    Solutions

  • Question 5/10
    4 / -1
    In the set up shown in Fig the two slits, S1 and S2 are not equidistant from the slit S. The central frings at o is then

  • Question 6/10
    4 / -1
    In Young’s double slit experiment, the two equally bright slits are coherent, but of phase difference π/3. If maximum intensity on the screen is I0, the intensity at the point on the screen equidistant from the slit is
    Solutions

  • Question 7/10
    4 / -1
    In an interference pattern produced by two identical slits, the intensity at the site of the central maximum is I. The intensity at the same spot when either of the two slits is closed is I0.Therefore
  • Question 8/10
    4 / -1
    Interference fringes are being produced on screen XY by the slits S1 and S2. In fig the correct fringe locus is

  • Question 9/10
    4 / -1
    In Young’s double slit experiment let S1 and S2 be the two slits, and C be the centre of the screen. If ∠S1CS2 = θ and λ is the wavelength, the fringe width will be
    Solutions

  • Question 10/10
    4 / -1
    Light of wavelength λ in air enters a medium of refractive index μ. Two points in this medium, lying along the path of this light are at a distance x apart. The phase difference between these points is
