what is coherence give me a example of this?

Coherent light -- light that is coherent. Usually produced from a laser. Incoherent light is light that is not coherent. It is produced from say, a lightbulb. Coherent light is light that is in phase with each other. InvertRect 16:57, 3 September 2006 (UTC)[reply]

What's well-defined light that can be defined? Isn't it overdoing it a little? How can you define well-defined, without using define? Is it possible to have well-defined light that can't be defined? Am I asking too many questions? Maybe I should just edit the word? What if it were deleted? Am I going insane? InvertRect 16:58, 3 September 2006 (UTC)[reply]
