“Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation.” - wacky-pedia

@@nickmalone3143 We can think of light either by its particle nature as you say, photons, but also you've probably heard of light waves. At the quantum level, most particles can be either waves or particles. When we think of light as a wave, the type of wave is indeed, electromagnetic. This is actually a great demonstration of the dual nature. An electron absorbs a photon of ultraviolet wavelength and jumps to a higher energy state. As the electron falls back to the lower energy , it emits a photon of a lower wavelength which is within the visible spectrum. So we end up with particles have different wavelengths. The dual nature of light. (I know I am kinda oversimplifying before any physicists start on me, but makes the point).

Spectroscopist here; Yes it IS fluorescence, and can correctly be classified as photoluminescence, as Ray said (Ray gets an A!). Luminescence can be from either fluorescence or phosphorescence, -- and fluorescence excited by the absorption of higher-energy photons (UV from Ray's light) is PHOTOluminescence. There's also chemiluminescence (from a chem. reaction), triboluminescence (from applied pressure -- ever chew some Wintergreen Canada Mints in the dark with your mouth open?), electroluminescence (electricity-induced), bioluminescence (from a living thing), thermoluminescence (temperature), etc etc. etc. Class dismissed!

Considering your hard ways, I just recalled a short reference in a late 1950's or early 1960's Reader's Digest. It told an argument between then princesses Elizabeth and Margaret and their home teacher about an impossible task. The teacher claimed nothing is impossible, if you try hard enough. On which the young smart ladies replied: Have you tried to put the excess tooth paste back into the tube?

On one hand, I loved my Jeep vehicles. On the other hand, they were constantly in the shop. Everything broke.

That's what I call quality. 8 year old vehicle and the A/C is already leaking. I used my 2004 Hyundai Santa Fe for 14 years, and it was still blowing freezing cold air with its original A/C charge. Never maintained the A/C system because it was running at peak efficiency when I donated it to the Salvation Army after 14 years and 195K miles of use.

That's a LUXURY Jeep. Thats a PERFECT example why i haven't bought a used vehicle in 30 years except for my 1996 Grand Cherokee and that had EXCELLENT service history. The new GC Summit is close to 70 grand, lots to spend on a vehicle. Did i miss the former collision damage??

I've found that on pretty much every modern car, removing the radiator, condenser and fan as a unit is usually the quickest way. I will say, this is the first time I've seen a trans cooler in the A/C condenser, rather than the radiator. Chrysler has been doing interesting things with A/C systems as of late. They also used the A/C system to cool the intake charge on the Demon.
