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.
