Harmonics? Standing waves? Let's rock & roll with strings and vibes! 🎸

🎈 Think of a child on a swing. If you push them at the right time (in sync with their motion), they swing higher. Similarly, when waves meet and reinforce each other, they make standing waves. If the waves are in sync, we get these cool patterns called harmonics.

🤔 But wait! How can a string have one end free? Imagine a Spiderman's web hanging vertically. The top end is attached, but the bottom end is free.

Key Takeaways

• Fixed end = always a node (like a frozen spot, no movement).
• Free end = always an antinode (like a party spot, maximum movement).

Real-life scenario: A guitar string! When you pluck it, one end is attached to the guitar (fixed), and the other end (where you pluck) vibrates freely (free end).
