Transverse and Longitudinal Waves

🧪Lab Brief #1

Transverse and Longitudinal Waves.

🎯 Your mission

Learn the rule. Then catch nature using it.

⚡ The twist

Nature loves to surprise the careful watcher.

🤯

Mind = Blown

🔬 The more you look, the more nature shows you.

🔮

Make a hypothesis first

Before you start: write down what you think will happen, and why.

What You'll Learn

Waves transfer energy without transferring matter. Transverse waves (like light) vibrate perpendicular to the direction of travel. Longitudinal waves (like sound) vibrate parallel.

Step 3 — Observe

Observe what happens and describe it in detail.

Step 4 — Record

Record your observations in your science journal with measurements and descriptions.
