a photographer wishes to use a safety light in the darkroom that will emit low energy photons the best color for this light would be
after randomly polarized light passes through a polarizing filter it is

the sky is blue because air molecules in the
act as tiny prisms dispersing all colors of light especially blue light
spectral lines in a line spectrum take the shape of lines because the
atoms that emit the light vibrate along a parallel line
the light from each element produces its own unique line spectrum this is because
each element has its own distinct configuration of electrons which emits distinct frequencies of light.
the frequencies of light emitted by atoms in the gaseous state are the fingerprints of those elements
Highest to lowest energy/frequency
