Question

how to find time period if frequency is 5hz and number of vibrations per second is 2

Answer 1

Answer:

The frequency formula in terms of time is given as: f = 1/T where, f is the frequency in hertz, and T is the time to complete one cycle in seconds. The frequency formula in terms of wavelength and wave speed is given as, f = /λ where, is the wave speed, and λ is the wavelength of the wave.

Frequency is expressed in Hz (Frequency = cycles/seconds). To calculate the time interval of a known frequency, simply divide 1 by the frequency (e.g. a frequency of 100 Hz has a time interval of 1/(100 Hz) = 0.01 seconds; 500 Hz = 1/(500Hz) = 0.002 seconds, etc.)

• 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.
