You would have seen beautiful colours in soap films or patch of oil
floating on the surface of water. Moreover, the colour gets
changed when you watch it from different angles. Did you ever try
to find out the reason? In scientific language, this takes place due
to the phenomenon of interference. The phenomenon of
interference of light tells us about the wave nature of the light. In
optics, the interference means the superposition of two or more
waves which results in a new wave pattern. Here, we are talking
about the interaction of waves emerging from the same source or
when the frequencies of these waves are the same. In the context
of light, which is an electromagnetic wave, we say that when thelight from two different sources moves in the same direction, then
these light wave trains superimpose upon each other. This results
in the modification of distribution of intensity of light. According
to the principle of superposition, this is called the interference of
light.

More precisely the interference can be defined as the interaction
between two or more waves of the same or very close frequencies
emitted from coherent sources (defined later), where the
wavefronts are combined according to the principle of
superposition. The resulting variation in the disturbances produced
by the waves is called the interference pattern. Thomas Young, in
1802, explained the interference successfully in his double slit
experiment.
