Question

Derick is fishing in the inlet when a large cruise ship passes by. He notices two waves from the ship crash into the shore every three seconds. What is the frequency of the waves?

0.3 Hz
0.6 Hz
1.5 Hz
2.3 Hz

Answer 1

The frequency of the waves observed by Derick is calculated based on the number of waves occurring per unit time. By dividing 2 waves by 3 seconds, the frequency is determined to be 0.6 Hz.

Step-by-step explanation:

The frequency of the waves that Derick observes can be calculated using the definition of frequency, which is the number of occurrences of a repeating event per unit time. In this case, the event is the waves crashing into the shore and the unit of time is seconds. Since Derick observes two waves every three seconds, the frequency (f) can be found using the formula f = number of waves / time. So, f = 2 waves / 3 seconds = 0.6667 Hz.

When rounded to one decimal place, the frequency is 0.6 Hz, making that the correct answer choice.

Answer 2

0.67Hz.

Step-by-step explanation:

One of the formulas for frequencies regarding periods (T), which is 3s, is f = 1/T

the one represents each cycle.

so in your case in 2 cycles the frequency is 0.67 Hz

because: f = 1/T

= 2/3

= 0.66...
