Wave Properties
Frequency (f)
Number of complete wave cycles per second. Measured in Hertz (Hz). Higher frequency = higher pitch for sound.
Wavelength (λ)
Distance between consecutive wave crests (or troughs). Measured in meters. Determines color for visible light.
Period (T)
Time for one complete wave cycle. T = 1/f. Measured in seconds.
Amplitude
Maximum displacement from equilibrium. Determines wave intensity and loudness for sound.
