Activity Launch the Wave on a String simulation again to investigate the relationship between amplitude and damping force.
To begin:
• Select Oscillate and No End.
• Set Amplitude to 1.00 cm and Frequency to 1.00 Hz,
• Set Damping to None and Tension to low.
• Select Rulers to measure the amplitude of the waves.
For each measurement described below, pause the wave when the oscillator arm is at or just past its maximum
Part A
You can see that each wave has a crest and a trough. Measure the amplitude at the first crest to the center of the ball and record your reading in
the table below. Record amplitude measurements for every subsequent trough and crest, as identified in the table.
Finally, vary the Damping as indicated in the table and record your amplitude readings again for each different damping value to complete the
table. Each division is 5 units of dampening force, where None = 0, and Lots = 50.
