Learning Event 1:
DESCRIBE THE VISIBLE SPECTRUM OF LIGHT INGREDIENTS
1.
The visible spectrum occurs when radiant energy of all wavelengths
between 400 and 700 millimicrons is presented to the eye in nearly equal
quantities, and the sensation of colorless or white light is perceived
(similar to the white light emanating from a black and white television
picture tube).
2.
The white light can be divided into component radiations by passing a
narrow beam of light through a glass prism (see figure 2-1). The resulting
band of colored light is called the visible spectrum of light in which the
principal colors are red, yellow-green, blue-green and blue.
