Nodes and Antinodes
"On pressing a switch we see loops magically appear on a vibrating string. Now, here's the cool part: when we play with the frequency using a regulator, the loops change! More loops show up when the frequency is higher.
How does this happen? Well, the waves traveling along the string bounce back at the ends. Imagine a wave going out and meeting its reflection—it's like a dance! This interaction makes it look like there are loops that aren't moving. In these loops, some points don't move much (we call them nodes), and the widest parts are where the action happens (those are antinodes). So, it's like the string is throwing a silent dance party with nodes and antinodes, all because of those reflected waves!"
