100
A type of energy that is measured in joules (J).
What is heat. (Heat is measured in Joules. In electricity, its energy (which is heat/light) is measured in Joules - but how strongly the electrons move is measured in volts; and the amount of electric charge (flow) is measured in amps).

What is magnetism.
200
The band of color in a rainbow.
What is spectrum.
300
A car's horn sounds different as the car approaches. The change of pitch is due to A) electromagnets. B) The Doppler effect. C) the absorption of sound. D) the creation of a vacuum.

300
Unit used to measure electrical energy.
What is Joules. (Heat is measured in Joules also. In electricity, its energy (which is heat/light) is measured in Joules - but how strongly the electrons move is measured in volts; and the amount of electric charge (flow) is measured in amps).
