  1. Quiz 4

  2. Radio Waves • What is the difference between AM and FM radio waves? • What kind of current is created by spinning a coil through a magnet?

  3. How Antennae pick up Signals The electromagnetic wave of the signal travels across the antenna, inducing current through the antenna.

  4. Transistors Roles Transistors pick up and amplify the signal. Transistors also act as switches to tell a car to turn right or left.
