An illustration shows the propagation of two waves for a period of one second. The first wave has a lower number of cycles than the second wave, but both the waves travel an equal horizontal distance in one second.

Answer 1

The bottom wave has a greater amplitude.

In this scenario, since both waves travel the same distance in one second, they have the same speed. However, the first wave has a lower number of cycles (lower frequency), so the second wave must have a higher frequency. Therefore, the answer is that the bottom wave has a greater amplitude.

Thus, the best response from your options is amplitude.
