Interference of waves:
When two waves of similar amplitude and period traveling in the similar medium superpose, they reinforce each other at one point and cancel at others. This phenomenon is called as the interference of waves.
(i) On the average, particles are separated by a distance of the order of 10-10 m and exert a force of attraction of the order of 10-11 N on each other. (ii) The force of atta
