Higher energy means shorter wavelength. Longer wavelength
= lower frequency = lower energy level (for photons). So
it's just the opposite, blue light is higher energy than
red, or more correctly, photons at bluer frequencies have a
higher energy level than photons at redder frequencies.
Violet is about .390-.455
and Red a whopping .622-.780 microns long
The top of this list is the higher energy (sorry for the
pun), and those sluggard red photons at the bottom of the
list barely wiggle at all, relatively speaking ;-)
I got the blues and can't be satisfied,
