Super position principle

It states that, ‘if large no of wave are super imposed with each other at any time. Then the displacement of resultant wave is sum of displacement of individual wave at any time.
Let y1 + y2 + y3……………….. + yn are the displacement wave which are super imposed at any time, Then the displacement of resultant wave at that time.
y = y1 + y2 + y3……………….. + yn
