प्रश्न
A simple pendulum makes 10 oscillations in 20 s. What is the time period and frequency of its oscillations?
उत्तर
Given, number of oscillations = 10
Time taken = 20 s
As, we know that the number of oscillations per second is frequency.
∴ `"Frequency" = ("Number of oscillations")/"Time taken" = 10/20 = 0.5` Hz
∴ `"Time Period" = 1/"Frequency" = 1/0.5` = 2s
