What has the shorter wavelength ultraviolet or infrared?
The infrared (IR) radiation has a longer wavelength (and a lower frequency) than ultraviolet (UV) radiation. The former is below the visible spectrum, and the latter is above that visible (sometimes called optical) spectrum. However, IR radiation does not have the longest wavelength in the Electromagnetic Spectrum. That would be the Radio Waves. Additionally,: The prefix Infra- suggests "standing under, sub-, inferior to" (IR: Standing under Red light waves) The prefix Ultra- suggests "standing beyond" Violet light waves

Why does quinine glow when placed under black light?
A substance such as quinine glows because when absorbed light photons release photons of another wavelength. When the absorbed photons are in the ultraviolet range and the triggered emission is in the visible spectrum, a substance will glow under black light.

Why does a poster glow under black light?
A poster glows under black light if there is white designs on it. Anything white glows under black light. The reason why is because those things have phosphors on them which can only be detected under black light.
Is the ultraviolet radiation from the sun higher or lower in frequency than radar waves?
Using an Electromagnetic Spectrum diagram, UV radiation has a frequency range around 1016 Hz. This is higher than the listed frequency ranges used for radar, which are under 1010 Hz.
Green rock glows under black light?
Yes, but it is not nesicarally green rock that glows under black light. Some rock are florescent and glow (under black light). Most of these rocks appear green, but not nesicarally all of them.
