red, blue, green
which color of light has the longest wavelength
how fast does light travel
300,000,000 meters per second
method of heat transfer where warm matter rises and cooler matter sinks

domain theory
name two ways to destroy magnetism
heat, impact
name two ways to increase the strength of an electromagnet
use an iron core, add more coils of wire, use more current
