lets slow down and keep this to one thread.

First I would like to remind you that an experiment proves nothing. An experiment can only provide data. Also remember almost everything believed to be fact 200 years ago has been proven to be wrong today. You throw the "fact" word around as if there are no questions left to be asked

The double slit experiment shows that the act of observation causes light to act differently. Do you think that it maybe the instrument of observation causing the light to act differently?

We measure light and place it on the electromagnetic spectrum between Ultra Violet and Infrared. This is a spectrum of wave lengths in an electromagnetic field or medium.

I am trying to get you to think rather than remember something that you read in in a text book or Wikipedia as these are the very texts I am questioning.
