Final answer:

To find the wave with the lowest frequency, we need to find the wave with the highest period. The wave with the highest period is option C, 8 megaseconds (Ms), which means it has the lowest frequency. (Option C).

Step-by-step explanation:

To determine which of the given waves has the lowest frequency, we need to understand the relationship between frequency and period. Frequency is the number of cycles or waves that pass a given point in one second. Period, on the other hand, is the time it takes for one complete wave to pass a given point. The relationship between frequency and period is that frequency is the reciprocal of the period, meaning that frequency (f) is equal to 1 divided by the period (T). So, to find the wave with the lowest frequency, we need to find the wave with the highest period.

Let's convert the given periods into seconds:

  • A. 8 s
  • B. 80 microseconds (μs) → 80 x 10^-6 s
  • C. 8 megaseconds (Ms) → 8 x 10^6 s
  • D. 800 kiloseconds (ks) → 800 x 10^3 s

Comparing the four periods, we can see that option C has the highest period (8 Ms), which means it has the lowest frequency. Therefore, option C has the lowest frequency among the four given waves.
