Forms of Communication
Biological Communication – communication that
takes place without the use of technology. Ex.
Speaking, facial expressions, and hand signals.

Wave Communication – forms of communication that move through air,
water, or outer space.
Sound waves – vibrations traveling through air, water or other
medium that can be perceived by the human ear.
Electromagnetic Carrier Waves – radio and TV programs are
converted into electrical signals. Signals are carried by
electromagnetic carrier waves. Audio converted back to sound
waves so we can hear.
Light Waves – fiber optic cables transmit signals using light. When
you take a picture, light waves from your subject bring the image to
your eyes and the camera lens.
Telecommunication – communication over a long distance. Satellites
are used to carry the messages.
