Day 172: Mechanical Waves Whiteboards

The final unit for Honors Physics is mechanical waves (including sound). After a couple of days of exploring mechanical waves with Slinkies, we prepared and presented whiteboards of our observations and conclusions. This group did an excellent job presenting their measurements regarding the effect that amplitude and pulse width has on wave speed:


I was pleased that after almost a year, students are getting more comfortable with the idea that, due to measurement uncertainty, different measurements may indicate that no relationship exists!
