ADDITION OF WAVES
In this section we will discuss the
interference pattern produced by the
superposition of two waves You may recall
that we had discussed the superposition
principle in Chapter 14 of your Class XI
textbook Indeed the entire field of
interference is based on the superposition
principle according to which at a particular
point in the medium, the resultant
displacement produced by a number of
waves is the vector sum of the displace-
ments produced by each of the waves
