If decrease in intensity is due to decrease in amplitude alone then you would not be able to see light sources billions of light year away. What is sad is that you runts don't realize that intensity is both amplitude and frequency dependent. Amplitude of a wave can be increase during generation whereas frequency of a light beam is distant dependent because of the inverse square law. I suggest that you go learn some physics before you put anybody in your self-assumed fumble page. |
