How can you relate pitch and frequency?

Short wave propagation of radio waves consists of freqeuncies which are reflected by ionosphere. Some important technical terms are defined related to the free electron density N of layers and the frequencies v to be reflected are mentioned in Column-I. They are related to frequency v and free electron density N as shown in Column-II
