The value of the pink wave is like, negative 3/4, so the value of the total wave would be positive 1/4. The distance between OA and OB are the same and hence, the waves starting from A and B reach O after covering equal distances (equal path lengths). It gives background information and further details on equations, linear media, superposition and reflection at boundaries between media with different properties. The superposition principle is important both because it simplifies finding solutions to complicated linear problems (they can be decomposed into sums of solutions of simpler problems) and because many of the fundamental laws of physics are linear.
