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.
When light comes across with a solid material, some of it is reflected, some of it passes through and some of it is absorbed. I understand the reflection and passing through, but I don't understand what happens when light is absorbed. Suppose that there is an enclosed box.
