wavelengths

As for chemistry, InGaN efficiency drops at longer wavelengths, and AlInGaP efficiency drops at shorter wavelengths, leaving a big efficiency trough in the green range.

Transcend is doing essentially the same thing, but the goal is to produce wavelengths optimal for plant growth instead of a broad spectrum for illumination.

The energy absorbed by interstellar gas and dust doesn't just disappear, it's re-emitted at (mostly) infrared wavelengths.

Microwaves would work to if you are careful about your wavelengths and don't point them at satellites.

Partial Dyson swarms can be detected by comparing the mag of a star at two different wavelengths.

In practice, it's difficult figure out exactly what these wavelengths should be, and to match them to existing high efficiency emitters.

Anyone have any idea what those 'scars' are that are only visible in x-ray wavelengths?

Instead of having sensors for different light wavelengths, you just pack more of them.

RGB camera sensors can't identify specific wavelengths, all they can tell you is that a given wavelength is in some specific range.

At specific wavelengths (~245-265 nm), (UV) light inactivates quite a few living things.

An ophthalmologist friend pointed out that unfiltered long term exposure to these wavelengths first catalyzes conjunctivitis (pink eye) then conditions go down hill from there.

They respond to those 3 critical wavelengths of light to allow the plant to guess the time of day and the season of the year.

Do you mean "which reflects or emits light of these particular wavelengths", or do you mean something about human perception?

Your computer monitor does not actually emit "a pure cornflower-blue wavelength", it exploits the limits of your vision and emits a mix of 2/3 wavelengths that simply seems the same.

Long cones are responsible for seeing long wavelengths ("λ") of the visible electromagnetic spectre ("EMS") are going towards Red and peak there before fading into infra-red.

So "time" would just be our way of perceiving a static causal relationship between atoms, in the same way that "color" is our way of perceiving wavelengths of light.
