1. Describe the relationship between the color change of the filament with temperature, and the colors in the observed spectrum of white light.
2. Order the colors of the rainbow according to the amount of energy needed to produce them, from lowest to highest.
1. Does this pertain to an incandescent bulb? Probably so. As T is increased, the filament goes from a very dull red to orange then to blue and to white. When it is white light all of the colors of the rainbow are visible if viewed through a dispersing instrument.
2. ROY G. BIV, a mans name gives the colors from lowest to highest energy.
red, orange, yellow, green blue indigo, violet. ultra violet is next and infrared precedes the list as the lowest energy.
Thank you SO much!
