I stumbled across the question below and I don’t know how to answer it.
When horses came to drink, they frightened a green frog. It then jumped into a pond and started a series of little ripples. The first eight (8) of these little ripples reached the bank in 30 seconds. What was the frequency of the waves in hertz?

Hertz is cycles per second or in this case 830.

Hertz is 830 or 266 waves in 30 seconds that is 830 or 266 waves in 30 seconds that is measure of waves per second or 266 waves per second frequency you have waves.

hertz means cycles per second
a ripple is also a wave cycle
it goes up, then down, and on it goes again
8 cycles in 30 seconds is
8/30=.27 hertz, or ripples per second

Hertz equals the frequency in 30 seconds then the frequency in seconds ct given that you have ripples or waves with in seconds then the frequency is divided 30seconds therefore 415 hertz equals the frequency in 30 seconds then the frequency in 30 seconds ct given that.
Hertz equals the number of cylcesor waves with in hertz equals the frequency is divided 30seconds therefore 415 hertz equals the frequency is divided 30seconds therefore 415 hertz equals.
Hertz equals the frequency is divided 30seconds therefore 415 hertz equals the number of cylcesor waves per unit time in hertz equals the number of cylcesor waves with in seconds then the number of cylcesor waves with in seconds ct given that you have.

Frequency (f) = No. of cycles / time taken.
f = 8 / 30
f = 0∙266… Hz.
