The physical distance between two consecutive points of a wave that are in the same phase, such as two peaks or two troughs. Wavelength is inversely proportional to frequency; higher frequencies have shorter wavelengths, while lower frequencies have longer wavelengths.
- A 440 Hz sound (A4) has a wavelength of approximately 0.78 meters in air.
- A sub-bass note at 50 Hz has a much longer wavelength, roughly 6.86 meters in air.
Wavelength is essential in understanding how sound waves interact with physical spaces, affecting phenomena like resonance, phase alignment, and acoustic treatment.
