Diagrams 1 and 2 show two sounds with the same frequency (wave spacing) but different amplitude (the height of the trace). The trace on 1 comes from a sound with a smaller amplitude than on 2.

In the following diagram the waves move from left to right and then stop. The motion of the waves lasts for two seconds. Figure caption, A 2 second wave with 2 peaks and troughs. Answer these ...

Notice, too, that the frequency of the incoming and outgoing signals are the same. Carrier Wave Generator The Wave Generator creates a high-frequency radio signal.
