Detailed explanation-1: -The frequency f = 1/T = /2 of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
Detailed explanation-2: -The period T and frequency f of a simple harmonic oscillator are given by T=2√mk T = 2 m k and f=12√km f = 1 2 k m, where m is the mass of the system.
Detailed explanation-3: -If it takes 12 seconds to undergo 5 vibrations, 12s5 12 s 5 is the time for one vibration, which is 2.4 seconds. The frequency is 0.42 Hz.
Detailed explanation-4: -The formula for period is T = 1 / f, where “T” is period – the time it takes for one cycle to complete, and “f” is frequency. To get period from frequency, first convert frequency from Hertz to 1/s. Now divide 1 by the frequency. The result will be time (period) expressed in seconds. 02-Feb-2023
