The sound from a honey bee is produced when it vibrates its wings at an average rate of 400 vibrations per second.
What is the time period of the vibration in milliseconds?
Problem: 2 Marks
1. Given that 400 oscillations are made by the pendulum for 1 sec
∴ Frequency = 400 Hz
2. Time Period= 1/Frequency = 1/400 = 2.5 ms
