It's All in the Name
Answer in the form of a question: the highest point on a transverse wave.
What is a crest?
A physics class decides to measure the period of a pendulum hanging from their ceiling. What are they actually measuring?
How long it takes the pendulum to swing back and forth
How many centimeters are in one and a half meters?
150
Which way do particles move in a longitudinal wave?
Back and forth, parallel to the path of the wave itself
What are our three units this semester?
Waves, Sound, and Light
Answer in the form of a question: the lowest point on a transverse wave.
What is a crest?
5.0916 Hz
How many Hz are in 0.34 kHz?
340 Hz
What do you call the part of a longitudinal wave where particles are squished together?
A compression zone
Name two examples of transverse waves in real life
Light waves, slinkies, ropes, etc.
Answer in the form of a question: stacking two identical waves on top of each other (not adding them! just putting one physically above the other) and measuring from the trough of one to the crest of the other gives you four of these.
What is amplitude?
What two variables does the period of a pendulum depend on?
Length and gravity
How many millimeters are in three kilometers?
3,000,000 seconds
What do you call the part of a longitudinal wave where the particles are stretched out?
A rarefaction zone
Name an example of a real-life wave that could kill you!
Tidal wave, tsunami, earthquake, etc.
Answer in the form of a question: a mass hung from a fixed point, that can freely swing back and forth.
What is a pendulum?
How do you spell the full name of the SI unit of frequency?
Convert 150 mm/s to m/min.
9 m/min
Name two examples of longitudinal waves in real life
Possible answers: sound waves, slinkies, earthquakes, starquakes, etc.
Name a sport that takes place on waves
Surfing!
Answer in the form of a question: LIGO measures these kind of waves.
Gravitational waves!
As a group, use your bodies to demonstrate to the class what a transverse wave looks like. You get 60 seconds to deliberate from the moment you open this question, and one try to do it!

Many chemistry conferences have held a 50-Trillion Angstrom (Å) Run. How long is this run in kilometers? (1 Å = 1 x 10-10 m) (1 trillion = 1,000 billion)
5 km

On what planet in the solar system would a 1m pendulum have the shortest period?
Jupiter
