Waves
Also known as: wave motion
A disturbance that transfers energy through space or a medium without transferring matter. Sound, light, earthquakes, and radio signals are all waves — understanding waves unlocks all of these.
💡 Intuition
Energy traveling through something—like ripples on water. The water stays put; the ripple moves.
Core Idea
Waves transfer energy and information through a medium without transporting matter itself.
🔬 Example
🎯 Why It Matters
Sound, light, earthquakes, and radio signals are all waves — understanding waves unlocks all of these.
⚠️ Common Confusion
The medium (water, air) oscillates in place; only the pattern moves forward.

How Waves Connects to Other Ideas
To understand waves, you should first be comfortable with energy and simple harmonic motion. Once you have a solid grasp of waves, you can move on to wavelength, frequency and amplitude.
