When two light waves of nearly same amplitude, same frequency and traveling in the same
direction of medium, superimpose over each other then there occurs variation of intensity of light
with distance (maximum and minimum). This phenomenon is defined as interference of light.
1. The experiment on interference of light was first performed by Young in 1802.
2. The energy or intensity of light gets redistributed non uniformly as a result of superposition of    the light waves.
3. Interference is observed in both longitudinal as well as transverse waves.
 4.In interference phenomenon energy in neither created nor destroyed rather there occurs
redistribution of energy in the form of maxima and minima.
