what is Frequency? How does frequency work.

 Frequency Explained. 

What is frequency? Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.

What are radio waves? 

Radio waves are part of a larger group of waves classified all together as electromagnetic radiation. This large group of waves is broken down into smaller groups based upon their frequencies and wavelengths. Two examples of electromagnetic radiation (other than radio waves) are:

• Light -- which is the group of electromagnetic radiation you can see with your eyes
• X-rays -- which are a group from a higher frequency and they are what is used by doctors to see inside of you

Below is an illustration of how electromagnetic radiation is broken down into groups. The section that covers radio waves is marked Radio Frequencies. The list of examples on the left is there to give you an idea of how long the wavelength is for that type of wave.
