What is a period?
The study of images formed by mirrors or lenses.
What is optics?
The process of forcing a charge separation using a charged rod in order to provide an "escape route" for excess negative charges.
What is charging by induction?
A description of the process of fission.
What is 1 nucleus splitting a part after being hit by a neutron.

The six types of simple machines.
What are levers, inclined planes, pulleys, wheels and axles, wedges, and screws?
The difference between transverse and longitudinal waves and examples of each type.
What are transverse waves have particles that move perpendicular to the medium like light and water waves, whereas longitudinal waves move parallel to the medium like sound and earthquake waves?
The secondary colors of light, the primary colors that form them.
What is magenta is made by red and blue, cyan is made by blue and green, and yellow is made by green and red?

What are long wires or ones with narrow diameters, light bulbs, and resistors?
The equation used to determine the potential energy, and the equation used to determine the kinetic energy of a system.
What is potential energy equals the the object's mass (in kg) by its height off the ground and the gravity of the atmosphere it is in, and kinetic energy is the object's mass (in kg) by its velocity squared multiplied by 1/2?
The two equations that can be used to determine a simple machines efficiency.
What is efficiency equals work output divided by work input times 100, or efficiency equals the actual mechanical advantage by its theoretical mechanical advantage times 100?
The equation used to determine the period of a pendulum.
What is the period in second (T) equals 2 pi times the square root of the objects length (L) by the gravity (g) of the atmosphere it is in?
