Understanding Wave Interference of Different Pulses

In this video, I walk through problem number 48 from chapter 11 of Giancoli Physics, focusing on oscillations and waves. I explain how to sketch the shapes of two overlapping pulses and discuss the concept of destructive interference. I also address where the energy is located when the string appears straight at a specific moment. Please pause the video to sketch your own answers before comparing them with mine.
