Question

A metronome vibrates so that it makes 5 cycles in 12 seconds. Calculate its period and its frequency (in Hz).

Answer 1

Answer :

Hz (Hertz) is the frequency unit of the vibration cycle time of electric, magnetic, acoustic and mechanical vibration, i.e. the number of times per second (cycle/sec). 1 Hertz means one vibration cycle per second, 50 Hertz means 50 vibration cycles per second while 60 Hertz means 60 vibration cycles per second.
