Be it red, white or yellow, roses convey so much alone or in a bunch, or matched with other, complementary flowers. If you learn a bit about the âfloriographyâ of the different colors of roses you can understand their true meaning and the color you choose can add special meaning to your gift.
White light contains all the wavelengths of the visible spectrum at  equal intensity. The different colors of light, except violet, are  absorbed when white light shines on â¦ an opaque violet object. The  violet color is reflected.
And there are some minerals that will glow when they are struck or crushed; this is called triboluminescence. The fluorescent minerals are those that emit visible light when activated by invisible ultraviolet light (UV), X-rays and/or electron beams. Certain electrons in the mineral absorb the energy from these sources and jump to a higher energy state. The fluorescent light is emitted when those electrons drop down to a lower energy state and emit a light of their own.
