1) Frequency: Sound waves have a specific frequency, which refers to the number of vibrations or cycles of the wave that occur per second. Frequency is measured in hertz (Hz) and determines the pitch of the sound. Higher frequencies result in higher-pitched sounds, while lower frequencies produce lower-pitched sounds.
2) Amplitude: Amplitude refers to the maximum displacement or distance of the particles in the medium from their equilibrium position as the wave passes through them. It determines the loudness or volume of the sound. Greater amplitudes result in louder sounds, while smaller amplitudes produce softer sounds.
3) Wavelength: Wavelength represents the distance between two consecutive points of a sound wave that are in phase. It is typically measured from the peak of one wave to the peak of the next wave. In general, longer wavelengths correspond to lower frequencies, while shorter wavelengths correspond to higher frequencies.
4) Speed: Sound waves travel through a medium at a specific speed. The speed of sound varies depending on the properties of the medium it passes through, such as temperature and density. In dry air at room temperature, sound typically travels at around 343 meters per second.
