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.
This is due to the amount of light being absorbed by the colour. The lighter the colour the smaller the range of visible light being absorbed and converted into heat. White objects reflect all visible light, where black objects absorb all visible light.
