My understanding of clear materials is that they allow all lower photon energies to pass through due to the energy gap.
This makes sense for UV proof glass, it blocks higher energy photons.
What I dont understand is how a material can only let a certain range of photons through, like most of the visible range but no infrared, because that means its blocking a lower energy level and allowing a higher energy level which doesnt make sense to me if the energy gap between electrons is what causes transparency.
Thanks.
Pic related because it was probably taken with an IR filter.

She's hot
I want to know the answer.

Then this is probably the wrong place to ask
Also, she's hot

Photons are only absorbed if their energy level is within the energy range of the filter. The average of the energy range of an IR filter is in the infrared and the range itself is around that level, not above.

I have conclusive proof

Light is a wave not a particle. (I know it's technically both but not always practically.)
Light filters work by blocking certain wavelengths. It has nothing, directly, to do with the energy of the photon beyond how that energy changes the wavelength of light.

There's more than one energy gap in a material.

ty for input
so IR filters have energy levels and or particles that block only IR light?
