In conventional light source, light comes from a large number of independent atoms, each atom emitting light for about sec i.e. light emitted by an atom is essentially a pulse lasting for only Light coming out from two slits will have a fixed phase relationship only for sec. Hence any interference pattern formed on the screen would last only for , and then the pattern will change. The human eye can notice intensity changes which last at least for a tenth of a second and hence we will not be able to see any interference pattern. In stead due to rapid changes in the pattern, we will only observe a uniform intensity over the screen.

Q.198. A tube of length l = 26 cm is filled with benzene and placed in a longitudinal magnetic field of a solenoid positioned between two Polaroids. The angle between the principle directions of the Polaroids is equal to 45°. Find the minimum strength of the magnetic field at which light of the wavelength 589 nm propagates through that system only in one direction (optical valve). What happens if the direction of the given magnetic field is changed to the opposite one?
