Principle of Superposition of Waves

The video tutorial explains the principle of superposition using wave pulses traveling in opposite directions on a string. It describes how the total displacement is the algebraic sum of individual displacements. The tutorial provides a mathematical explanation and an example involving waves with a phase difference. It concludes with a calculation of the resultant wave using trigonometric relations, highlighting how phase differences affect wave amplitude.
