Waves can be transverse (perpendicular) or longitudinal (parallel).
Sound waves are longitudinal.
Sound waves are longitudinal waves that require a medium to travel through, such as air or water.
The frequency of a wave refers to how many complete cycles occur per second.
The speed of sound is determined by the medium through which it travels, with faster speeds in solids than liquids and gases.
Frequency determines pitch, while amplitude determines loudness.
Pitch is determined by the number of vibrations per second, measured in hertz (Hz), while loudness is determined by the intensity of the sound, measured in decibels (dB).
