Can some minerals glow under ultraviolet light?
Yes. Only certain minerals will glow under ultraviolet light. First you have to have the uv light shining on it, then you have to turn the lights off and they will grow
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
How do you get things to glow under a black light?
Black light is only black because very little of the light the lamp produces is in the visible spectrum. Most is actually ultraviolet (UV) light. The frequency of such light is just a little higher than violet (hence the name ultraviolet). The human eye cannot detect UV light, so black light is mostly invisible to us (you might see a faint violet glow however). UV light can cause certain materials to glow due to an effect called Fluorescence. This entails a material absorbing light at a certain frequency (e.g. UV light) and retransmitting it at another frequency, for example visible light. We cannot see UV light but we can see the retransmitted visible light causing the object to glow. Black light theaters make good use of such materials, but in many countries the paper money also contains fluorescent materials. That is why people working behind the counter in shops will sometimes hold money under a UV lamp; counterfeited money might not have such security features and will thus reveal itself for the fake it is.
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.
How do reflective materials work?
Ultraviolet rays from car headlights or street lamps reflect the reflected areas and makes the colour glow.add Light may be reflected from a surface, and the apparent colour of the surface is due to the absorption of all the other colours.If a surface is smooth compared with the wavelength of the incident lightwave, then an image may be seen reflected from the surface. [About 1/20 of a wavelength would be good.] If the surface is also shiny, then a good mirror will be had.Alternatively, if the surface were covered with tiny clear glass or plastic beads, then a total internal reflection will be observed. This is the reflectorized jacket application and similar. The equivalent of the Brocken spectre, or the mist halo effect. The beads reflect essentially all the light they receive, back in the direction from which the light arrived.Some materials may be made to fluoresce - to emit light at a wavelength other than the incident one. These materials will appear to glow, and this effect is often obtained under ultraviolet light light (black light).
