The sound wave is a type of compression or longitudinal wave. In a

compression or longitudinal wave the vibrations happen in the same direction as the

wave's velocity. A compression or longitudinal wave looks like this:

1) Areas of compression (high pressure), 2) areas of rarefaction (less pressure), 3) the wavelength, 4) the direction of the velocity.

Waves have to have to have a medium to travel through and travel best through solids. Waves are a way to transfer energy from one place to another.

The frequency is the length of one cycle of a wave. The frequency determines the

The amplitude determines the loudness. The amplitude is when the signal goes through an amplifier, which makes the signal louder and stronger. Radio waves move 186,000 miles per second.

Circuit, it wasn't possible to receive more than one station in the same place, because the transmissions of stations would interfere with each other. Another problem was that you couldn't even select the signal on reception.

In 1901 Marconi launched a kite for supporting the receiving antenna in Newfoundland. This closely resembles a satellite. Now there are communication satellites, which receive radio signals from one part of the earth and transmit it to another part of the earth. A transmitting antenna radiates signals from the transmitter as radio waves. The radio waves vibrate up and hit the communication satellite and are transmitted to another part of the world.
