Discuss the condition for sustained interference
Asked by Topperlearning User | 12 Jun, 2014, 12:37: PM
answered-by-expert Expert Answer

In order to produce a stable interference, the following conditions should be satisfied:-

  • The two sources must be coherent.
  • The waves that are interfering must have approximately the same amplitude, otherwise the resultant            interference pattern will lack contrast.
  • The Light must be monochromatic. Otherwise, the fringes of different colours will overlap.
  • The two sources must be close to each other. This will enable a large fringe width.
  • The two sources must be narrow.
  • The two sources should emit waves continuously.

In Young's double slit experiment, the two slits are separated by 0.28mm and the screen is placed at a distance of 1.4m away from the slits. the distance between the centre fringe and the fifth dark fringe is measured to be 1.35cm . calculate the wavelength of light used. Also find the fringe width if the screen is moved 0.4m towards the slits, for the same experiment set up.

if separation between the two slits is increased till fringes are observed then what will happen to angular separation of fringes (my thought is here  fringes are not observed  and they are increasing till fringes show up ...so until then what will happen to angular width if we increase d-slit separation..does angular width increases or remains same

We for equal wave intensities the intensity at a point is given by straight I to the power of apostrophe equals 4 Icos squared open parentheses straight ϕ over 2 close parentheses but where does the formula straight I to the power of apostrophe equals Icos squared open parentheses straight ϕ over 2 close parentheses come from??
