Step 1

3. Transverse Waves
In a transverse wave, the wave moves at a right angle (perpendicular to) the direction of the spring.

4. SPRING CARE GUIDELINES
The spring is a delicate piece of science lab equipment that you are entrusted with.
Transport the spring in its box to and from the materials station.
At all times, keep the spring entirely in contact with the table surface.
The spring should never be dangled or waved through the air.
If a spring accidentally becomes tangled, immediately call your teacher over to assess the situation.

6. Parts to Label in Your Diagram
Crest – Top of the Wave
Trough – Bottom of the Wave
Midline – Line through the Middle of the Wave
Nodes – Points at which the wave crosses the midline

8. Discuss transverse waves
Waves Course, 1.2: Spring Waves
Discuss transverse waves
Add labels to diagram.
Step 10

9. Measurements to Label in Your Diagram
Wavelength (λ)– Distance from one crest to the next (or one trough to the next)
Amplitude – Distance from the midline to the crest (or trough)
