UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.

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 is some examples of ultraviolet light?
sun
Does acrylic block uv rays?
Ultraviolet rays are blocked by all solid materials except for solocryl or starphire glass. Some acrylic materials are made specifically to block ultraviolet rays.
How do you see ultraviolet waves?
Ultraviolet light is not visible. Many ultraviolet lamps also emit some visible light along with the ultraviolet, typically visible violet. Also, ultraviolet light is an ionizing radiation, and will cause some flourescent materials to emit various visible wavelengths of light.
What are materials that transmit some light?
The word for materials that transmit some light is translucent.
What three minerals glow under ultraviolet light and what is that glow called?
Some minerals that glow under ultraviolet light are scheelite, amber, halite.
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
How are some corals fluorescent?
Do you mean, "Why does coral glow in ultraviolet light?", "Why does some coral glow in the dark?", or something else. Please be more specific.
What are 3 minerals that glow under ultraviolet light?
Three minerals that glow under ultraviolet light are calcite, fluorite and sheelite. Sheelite gives a bright blue glow. Calcite can give various colors like red, green, pink and orange.
What are phosphorescent materials?
These materials absorb light energy in the day and they are able to give off this energy in the dark or at night. Some examples of these materials are glow in the dark stickers, glow in the dark watches and glow in the dark bouncy balls.
Why do some scorpions glow?
In ultraviolet light, some types of scorpions glow blue. Their exoskeletons are reacting to a type of light that human eyes can't see. Scientists are not sure just why this happens to scorpions. One theory is that the glow warns them when parts of their body aren't properly hidden, and could give them away.
How do you see ultraviolet light?
Humans do not see ultraviolet light, but there are some who can who have had to have replacements in their eyes, which altered their vision so that they can.
What are some disadvantages of ultraviolet light?

What are luminous and non luminous materials?
Luminous means "giving off light", or glows in the dark (since luminosity is detected by the eyes, it usually refers to the visible part of the electromagnetic spectrum). Many materials emit a wide range of radiation other than visible light, which is why some radioactive materials were used as glow in the dark paints, and why the Curies focused on a particular radioactive isotope (because it glowed in the dark). Some materials can even store energy from visible light and emit it later, which is why some of my luminous objects have to be "charged" by a light bulb or the sun. Some chemical combinations can emit light for a while, such as the stuff in lightning bugs, which we can replicate in production lines to make glow sticks. Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category.
