The easy way to shed light on Optics In general terms, optics is the science of light. More specifically, optics is a branch of physics that describes the behavior and properties of light?including visible, infrared, and ultraviolet?and the interaction of light with matter.

Learn to:

• Use optics principles and devices properly
• Avoid common mistakes in working with typical optics problems
• Determine image locations and characteristics with simple calculations
• Grasp the basic concepts behind lasers and laser applications

An illuminating exploration of optics and optical technologies

Get turned on to the study of light with this friendly guide to the world of optics.
