C.2.3—Wave equation Topic Practice
Apply the wave equation to calculate speed, frequency, wavelength or period from graphs, resonance geometry and sound data.
How this is tested
- use v = f lambda or v = lambda/T after extracting two quantities from a graph or data table
- combine resonance lengths with unchanged frequency to calculate wave speed in another medium
- keep units consistent and give the final speed to appropriate significant figures
