Why does fireflies admit light that has no heat? in other words, "cool lights"?
Answer:
Lampyridae is a family in the beetle order Coleoptera, members of which are commonly called fireflies, lightning bugs, or glow worms due to their conspicuous nocturnal (or, more accurately, crepuscular) use of bioluminescence to attract mates or prey. The firefly is capable of producing a "cold light" containing no ultraviolet rays, with a wavelength from 510 to 670 nanometers, pale yellowish or reddish green in color, with a lighting efficiency of 96%.Light production in fireflies is due to a chemical reaction that occurs in specialized light-emitting organs, usually on the lower abdomen. The enzyme luciferase acts on luciferin in this organ to stimulate light emission. This reaction is of scientific interest. Genes coding for these substances have been inserted into many different organisms (see “Applications” in Luciferase). Luciferase is also used in forensics, and the enzyme has medical uses.
Chemical reaction between the chemical luciferin, and the energy carrier adenosine triphosphate, energizes an electron in the luciferin to a higher state, and a photon is released when the electron returns to the ground state.
I think you mean "emit" no heat.
And that isn't true. The light emitted has a certain amount of energy to it that when absorbed by your skin will be transformed into heat.
Light is often made by heat like in an traditional light bulb which is why you might think that light and heat need to be produced at the same time.
But to make light all you need to do is bump electrons around. You can do this with radiation, heat, electricity or by chemistry which is what the firefly does.
If the lights are cool, which I didn't know, its probably because of the certain chemical reaction that happens with in, and the light that it admits doesn't give off heat because all of it is reflected on any surface. However, that would mean the light would go on forever, so it must transfur its energy in a different form then heat, maybe it directs the energy straight to teh atom in form of atomic eneregy.
Think about the wavelength, the visible energy is green. All living creatures emit a visible aura which is also light with no heat. Actually the light from a firefly does produce a small amount of heat, this type of light is produced from chemical frequencies, not from other processes such as superoxidation.
