Unformatted text preview: Frequency We will explain frequency using a squirt bottle. First we will start with a cycle. A cycle is the changing event that creates the different radio frequencies. Imagine we are holding the squirt bottle level, then as we sqeeze the trigger moving our arm up and then down, then back to where we started, this is one cycle. Now notice as we move the sqirt bottle up and down, moving our arm up and down slowly creating long waves. If you move your arm up and down quickly we will get smaller but more rapid waves. The waves will vary in size and length depending on the way you move your arm. Radio waves work the same way. The rate at which the event occurs ( moving the squirt bottle up and down) will create different radio waves. This is how radio wave frequencies are created. Frequency is how frequent an event occurs. There are many things that can change the frequency. The amount of pressure you squeeze the trigger with we will use to represent the Voltage (V). We will consider the water flow to be the current, which with we will use to represent the Voltage (V)....
