    The power per surface area as a result of diffuse reflection of incoming light, what is it called?
    The electrons are excited by the incoming light and when returning to their ground states they emit the light we perceive as diffuse reflected.
    Is it the "leaving" which become "exit", or is it the "excitation" which become "excit"?
    /Best wishes!

    Edit: Well, I suppose the correct one is "exitance", since that is what they use in my book about introductory optics. The word could then be explained as "leaving along a ray" or something similar, which is allright to me! :D
