    From Michael Uplawski@21:1/5 to All on Wed Dec 11 13:31:35 2024
    Good afternoon.

    My question first: Is it possible to measure the wavelength of the
    light emitted or reflected from a surface in a way that would be
    practicable for just anybody, and with objects that would have to be “tested” all few minutes?

    I doubt it (knowing nothing, however).

    There are many difficulties that I can imagine and even more in the
    context of my professional activity, where I could benefit from such
    a technology ..:

    Yesterday I was separating green apples from those which approached
    a color that could be typical for a variety. I do this under neon
    lamps but the light from outside gets in and those apples that I
    discarded yesterday evening looked quite acceptable today.

    Green is just another problem, I guess. I have no idea if the Green
    of an apple is a pure color or a mixture that could in any way be
    evaluated as corresponding to something well determined.

    PSE take into consideration that all that I write above is based on assumptions. The question is really the on on top. Do not try to
    attack each false idea that I may have produced.., there are so many
    yet to present, the thread would explode … ;)

    Thank you in any case.
