If the frequency of a simple pendulum is 2 Hz, how many oscillations will it complete in 16 seconds?

Frequency is defined as the number of oscillations per second. If the frequency is 2 Hz, the pendulum completes 2 oscillations every second. Therefore, in 16 seconds, the total number of oscillations is 2 × 16 = 32. This is a direct application of the formula: number of oscillations = frequency × time.
