A student shakes a rope such that 20 complete vibrations are made in 4.00 seconds. Determine the vibrational frequency of the rope, along with the corresponding unit.

The vibrational frequency of the rope is 5 Hz.

Explanation:

Given;

number of complete oscillation of the rope, n = 20

time taken to make the oscillations, t = 4.00 s

The vibrational frequency of the rope is calculated as follows;

Therefore, the vibrational frequency of the rope is 5 Hz.
