Video transcript

Welcome back everybody. A Titan Clothes Line emits a frequency of 55 Hertz. And we are tasked with finding what is the period of the waves on the clothes line. Well, the formula for the period is simply just one over the frequency. So let's go ahead and plug in our number here. We have that. Our period is equal to one divided by 55 which when you plug it into your calculator gives us 0.18 seconds which corresponds to our final answer. Choice of B Thank you all so much for watching. I hope this video helped. We will see you all in the next one.
