What are sound and frequency?
“Sound is a longitudinal mechanical wave of any frequency.” “Frequency is the number of cycles.”
“Frequency is the rate at which something occurs or is repeated over a particular period of time or in a given sample.”
“Frequency is the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.”
“For an oscillating or varying current, frequency is the number of complete cycles per second in the alternating current direction. The standard unit of frequency is the Hertz, abbreviated Hz. If a current completes one cycle per second, then the frequency is 1 Hz; 60 cycles per second equals 60 Hz (the standard alternating-current utility frequency in some countries).”
“Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is 1/2 second, the frequency is 2 per second.” Cite error: Closing
