Waves launch lab

Shake the wrench up and down. What do the beads do?

• They break

• They fall off

• The make a wave

• The stay the same

How do you make the wave wider?

• Only move the wrench a little

• Move the wrench a lot

• Move the wrench slowly

• Move the wrench quickly

Start with the simulation like this. (oscillate and 0.4 amplitude). Increase the amplitude. What happens to the wave?

• It gets shorter

• It gets taller

• It gets wider

• It gets skinnier

Increase the frequency. What happens to the wave?

• It gets shorter

• It gets taller

• It gets wider

• It gets skinnier

How do you make the wave shorter

• Move the wrench a little bit

• Move the wrench a lot

• Move the wrench slowly

• Move the wrench quickly

Increase the damping. What happens?

• The waves start normal then get smaller

• The waves start normal then get bigger

• The waves start normal then go backwards

• The waves start normal and stay normal

Change from oscillate to pulse up at the top. Click the pulse one time. How many waves appear?

• 1

• 2

• 3

• 4

Click the restart button. Now change from oscillate to pulse. Turn the damping to none. What happens to the wave?

• The wave gets smaller

• The wave bounces back

• The wave gets bigger

• The wave gets faster.

Click on Loose End. How did the wave change?

With the damping at none, and loose end, change back to oscillate. What happens.

• The waves get smaller

• The waves get bigger

• The waves get wider

• The waves get skinner
