Question

State and explain the principle of superposition of waves.

Answer 1

here is your answer

The principle of superposition may be applied to waves whenever two (or more) waves travelling through the same medium at the same time. Thewaves pass through each other without being disturbed. The net displacement of the medium at any point in space or time, is simply the sum of the individual wavedisplacements.

hope you understand

Answer 2

Answer = When two or more waves traveling through a medium arrive at a point of the medium simultaneously,each wave produces its own displacement at that point independent of the other. Hence the resultant displacement at that point is equal to the vector sum of all the waves

Mathematically,y=y1+y2 {for two waves in same phase}

y=y1-y2{for two waves in opposite phase}

Where,

Y1=displacement of the particle due to the first wave

Y2=displacement of the particle due to the second wave

Y=result displacement of the particle after superposition of the two waves

The physical effect produced due to the superposition of waves is called interference
