# Finding the period of sinusoidal wave in rope

Hi,
i have a solution to the following problem but i'm not sure if it's right or not.
If you shake one end of a taut rope steadily three times each second, what would be the period of the sinusoidal wave set up in the rope?
Me, I thought that since I'm shaking the rope three times a second, this would be equivalent to three cycles per second, therefore if i want to find the period (cycles/1 second) I would just have 1/3 cycles/1 second. Did I do this correctly, or is it just horribly wrong? I would really appreciate it, thanks.

I really need to know if i'm right or not, that way i can move on with my studying...

When I shake the rope, would it really create only one cycle at a time?

If you have 3 cycles per second, each of them takes 1/3 of a second. So the period would be 1/3 of a second.
