RELATION BETWEEN THE PERIODIC TIME AND FREQUENCY:
FREQUENCY IS THE RECIPROCAL OF PERIODIC TIME
(INVERSELY PROPORTIONAL RELATION)

Periodic time =

Frequency x Periodic time = 1

EXAMPLE .1

Find The Frequency Of Oscillating Body Makes 180 Complete Vibrations In A
Half Minute?

<<Solution>>
Number of cycles 180
Frequency = = = 6 Cycles/Sec(6 Hz)

Time in second 0.5  60

EXAMPLE .2

An Oscillating Body Makes 180 Complete Oscillations In A Certain Time. Find

That Time If The Frequency Equals 6 Hz?

<<Solution>>

Number of cycles 180
Time in second = = = 30Sec.

Frequency 6
