A marine Weather reports waves along the shore that are eight seconds apaart. The frequency of the waves is therefore___ Hertz.

To calculate the frequency of the waves, we need to use the formula:

Frequency (f) = 1 / Period (T)

Given that the waves are eight seconds apart, we have the period (T) as 8 seconds.

Now, let's plug the values into the formula:

f = 1 / 8 seconds

By dividing 1 by 8, we can determine the frequency:

f = 0.125 Hz (rounded to three decimal places)

Therefore, the frequency of the waves along the shore is 0.125 Hz.
