Final answer:
The frequency of the clock is 0.6 Hz and the period is 1.67 seconds.
Step-by-step explanation:
The frequency of a wave is the number of oscillations per unit time, measured in hertz (Hz). The period of a wave is the time it takes for one complete oscillation. The relationship between frequency and period is given by the equation:
T = 1/f
Where T is the period and f is the frequency.
In this case, the clock ticks 3 times every 5 seconds. So, the frequency of the clock is 3/5 = 0.6 Hz and the period of the clock is 1/0.6 = 1.67 seconds.
