The unit hertz (Hz) for the frequency of the mechanical wave is the reciprocal of its period is in seconds. For this problem, the frequency of the wave is the reciprocal of 5 seconds. Thus, the answer is 0.2 Hz.

Answer:

0.2 Hz

Explanation:

The frequency of a wave is related to its period by the following equation:

[tex]f=\frac{1}{T}[/tex]

where

T is the period of the wave

f is the frequency

For this mechanical wave we know the period, T = 5 s, therefore we can apply the formula to calculate the frequency:

[tex]f=\frac{1}{5 s}=0.2 Hz[/tex]
