Question

State and explain principle of super position of wave

Answer 1

Answer:              

        principal of superposition of wave

The principle of superposition states that, when two or more waves of the same type cross at some point, the resultant displacement at that point is equal to the sum of the displacements due to each individual wave.

When superposition occurs, for slow mechanical waves the amplitude can be observed. For high frequency waves, such as sound or EM waves, the intensity is usually measured, which is a measure of the energy of the wave in the region: the energy is proportional to the square of the amplitude, Intensity∝∝2.
