Unifying Concepts and Processes

The electromagnetic spectrum is generally separated into different radiation categories defined by frequency (units of Hertz) or wavelength (units of meters). Wavelength is commonly represented by the symbol .

Example:

Name Approximate
Wavelength (m)
Xrays 10 -15 to 10 -9
Ultraviolet 10 -8 to 10 -7
Visible Light 10 -7 to 10 -6
Infrared 10 -6 to 10 -3
Microwave 10 -3 to 10 -1
Television 10 -1 to 1
AM Radio 10 -2 to 10 3

An impressed force is an action exerted upon a body, in order to change its state, either of rest, or of uniform motion in a straight line. A body force acts on the entire mass as a result of an external effect not due to direct contact; gravity is a body force. A surface force is a contact force that acts across an internal or external surface of a body.

Velocity is the rate at which the position of an object changes with time; it is a vector quantity. Speed is the magnitude of velocity.
