C.1.8 (HL)—Phase angle Topic Practice
Use phase angle to compare oscillations, convert path separation into phase difference and read leads or lags from sinusoidal graphs.
How this is tested
- use phase difference = 2pi x/lambda to calculate phase from a wave diagram separation
- state from SHM equations or graphs that acceleration and displacement are pi out of phase
- sketch a shifted sinusoidal graph with unchanged amplitude and period but a stated phase lag
