Mam, What is the interference of light?
Asked by Milind Shrivastava | 28 May, 2012, 11:27: PM
Expert Answer
 interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are correlated orcoherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example,light, radio, acoustic, and surface water waves. It is actually a phenomena in which a light wave from two or more openings spaces strikes an opposite surface , the pattern observed is in form of dark and lightpatches due to the high or low amplitude of light respectively.

A parallel beam of light of wavelength 600 nm is incident normally on a slit of width 0.2 mm. If the resulting diffraction pattern is observed on a screen 1 m away, find the distance of (i) First minimum, and (ii) Second maximum, from the central maximum.

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
