The minerals glow.
If you put them under ultra-violet light it changes color and glows.
Umbrella can block more than three-quarters of ultraviolet light
The property that describes how a mineral's surface shines is called luster. Luster refers to the appearance of light reflected off a mineral's surface, and can be categorized as metallic or non-metallic.
There is a form of phosphorus ("white phosphorus") that emits a faint glow when exposed to oxygen because of a chemical reaction taking place on its surface. So, the answer is "yes, phosphorus does glow in the dark" but only certain types of phosphorus, and only if the darkened room its in has oxygen in it. =)
Fluorescent light bulbs use phosphors to convert ultraviolet light into visible light.
It shines by the light.
It illuminates and gives warmth.
If you put them under ultra-violet light it changes color and glows.
Short-wave ultraviolet light (UV-C, 100-280 nm) is best for viewing fluorescent minerals, as it provides the most intense fluorescence. Medium-wave ultraviolet light (UV-B, 280-315 nm) can also be used, but the fluorescence will be less intense. Long-wave ultraviolet light (UV-A, 315-400 nm) is not ideal for viewing fluorescent minerals as it may not excite the fluorescence as effectively.
Ultraviolet (UV) light is used to identify fluorescent minerals. Specifically, shortwave ultraviolet (UV-C) and longwave ultraviolet (UV-A) light are commonly used in mineral identification due to their ability to cause fluorescence in certain minerals when exposed to them.
Ultraviolet light can cause certain minerals to fluoresce or emit visible light. By shining ultraviolet light on rocks, minerals that fluoresce can be easily identified and distinguished from other non-fluorescent minerals, aiding in their detection and identification. This property of minerals is harnessed in the field of mineralogy for exploration and research purposes.

When light shines through a prism, it is refracted, which means it is bent as it passes through the prism. This bending of light causes it to separate into its component colors, creating a rainbow spectrum.
it reflects violet and absorbs the other colors
When light shines on a translucent object, some of the light is scattered and absorbed by the material, while the rest passes through. This gives the object a softer appearance compared to transparent objects, as the light is diffused as it passes through.
When red light shines on a prism, it will refract and disperse into its component colors (red, orange, yellow, green, blue, indigo, violet) due to their different wavelengths. This creates a spectrum of colors known as a rainbow.
