Question

An object completes 120 oscillations in 1 minute. Find (1) Frequency (2) Time Period​

Answer 1

120 oscillations in 1 minute

➡️ 120 oscillations in 60 seconds

➡️ 2 oscillations in 1 second.

Frequency = no of oscillations in 1 second..

(1) Frequency = 2 hz.

➡️time period = 1/frequency

➡️time period = 1/2 seconds

Hope it helps ☺️☺️

Answer 2

Frequency= no of oscillation per second .

➡Time period = 60/ 120 = 1/2 sec.

➡Frequency= 120/60 = 2 Hz

* Frequency = no of oscillation/ time taken
