AMPLITUDE
Also known as wave height~ determines the volume of a sound.
The higher the amplitude of a sound wave, the louder the sound.
Amplitude ismeasured in decibels (dB).
WAVELENGTH
Distance between two wave peaks~ determines a sound’s pitch, or how low or high it sounds.
A sound wave with a shorterwavelength creates a higher-pitched sound than a sound wave with a longer wavelength.
Wavelength is measured in meters (m).
FREQUENCY
A measurement of how often a wave repeats in a certain amount of time.
Frequency depends on the wavelength ofthe sound wave and its speed.
Frequency is measured in Hertz (Hz). A wave with a frequency of 1 Hz repeats one full cycle per second.
