Question

A simple harmonic oscillator takes 13.5 s to undergo five complete vibrations. Find the period of its motion. Answer in units of s.

Answer 1

Period is the time taken for one complete oscillation in a harmonic motion.

Five oscillations take 13.5s

Period= total time for the n vibrations÷ the n vibrations.

Then one oscillation will take 13.5s÷5=2.7s

Therefore the period of the this motion is 2.7s
