Transverse and Longitudinal Waves

Lab Brief #1

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

Nature loves to surprise the careful watcher.

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.

Key words

frequency
How many waves or vibrations happen each second.
reflection
When light bounces off a surface, like a mirror.

Make a hypothesis first

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

Say your guess out loud — then find out if you were right.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Conduct a design challenge: build a car powered only by a balloon. Measure how far it travels and iterate on your design at least twice.

Step 3 of 4 · Observe

Draw a detailed diagram of what you observe.

Step 4 of 4 · Record

Write a conclusion: what did your results show? Did they match your prediction?

Question 1 of 3

What type of wave is sound?

How sure are you?😐 maybe

Question 2 of 3

Can sound travel through a vacuum?

How sure are you?😐 maybe

Question 3 of 3

What is sound?

How sure are you?😐 maybe

Mind = blown

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

Nice work!

You got 0 of 3 right.
