Explain the Interference of Light.

When two light waves superimpose, then the resultant amplitude ( or intensity ) in the region of superposition is different then the amplitude of individual waves. this modification in distribution of intensity in the region of superposition is called inerteference. 
When the resultant amplitude is the sum of the amplitudes due to two waves, the interference is known as constructive interference and when the resultant amplitude is equal to the difference of two amplitude, the interference is known as destructive interference.


Types of interference-
i) Division of Wavefront
ii)Division of Amplitude
