what color is the least refracted? (most common form of treatment)
red (infrared region) - most heat
what changes occur with UV radiation?
chemical changes
what are examples of utlraviolet regions?
X-ray, alpha and gamma rays
temperature does/does not equal the amount of heat.
does not
greater the heat difference, the greater the _____ change
