Ray of light. *Beam of light. A ray of light is a small linear portion of light. Itmay be of any color. A beam of light is a linear portion of light composedof a number of ravs. Prismaticcolors. White light, that is, sunlight, is composed of vaiiouscolors, as is easily shown by placing a prism in thepath of a small beam of sunlight. The prism separates the differentcolors that compose white light, and produces what is known as theprismatic or solar spectrum, as shown in the illustration. ORANGE. These colors are the same, and their arrangement is in the sameorder, as in the rainbow. Objects have no color in themselves, but they possess the powerof reflecting waves of light; and it is the waves of light of varyinglengths that give us the effect of color. It is the amount of motion of the ether, or height of the wave, thatproduces the intensity or brightness of the light, and the length ofthe wave that produces the color ; thus red has a wave length ofabout 2 5o7oo°o0ooo of an inch, orange ^somoooo, yellow s^ooooo, green __ 6 27 2 _ 2500000091 blue 2 50000000; and violet ^soodoooo a^^H^^^HaH^BmMHH^BraH^B^HHH^HBBB^^M^HMnH^HSM^^BMMa Colors innature. Since the different kinds of light are transmitted with equalvelocity, violet light makes more vibrations in the same length oftime than red light. Colors of Tne colors of objects are due to the power they objects. possess of absorbing c
