Question

A wave source produces 10 oscillations 100ms. Find the time period of the wave

Answer 1

A pendulum makes 40 oscillations in 4 seconds. find its time period and frequency.
Given that 40 oscillations are made by the pendulum for 4 sec. So, It makes 10 oscillations are made by the pendulum for 1sec. We know that the number of oscillations made per second (10 oscillations per second ) is called its frequency ∴ Frequency = 10 Hz Time period = 1/ Frequency Time period = 1/ 10 Time period = 0.1 sec
