TRANSCRIPT
Seed Question: What is a standing wave? Demo.
Exploration: You can think of standing waves as waves traveling back and forth, reflecting off the ends.
Sketch standing waves with fixed ends a distance L apart.
Standing Waves Lab
Take data on the five different standing waves to calculate their speeds. Use the expression you derived in the previous wave entry.
Data:
Length L(m)
Number of humps
Wavelength (m)
Cycles n Time t(s)
Frequency f(Hz)
speed v(m/s)
12345
What can you conclude about the speed of waves of different frequencies in the same medium?
Big Idea:
