An action spectrum is the rate of a physiological activity plotted against wavelength of light. It shows which wavelength of light is most effectively used in a specific chemical reaction. Some reactants are able to use specific wavelengths of light more effectively to complete their reactions. For example, chlorophyll is much more efficient at using the red and blue spectrums of light to carry out photosynthesis. Therefore, the action spectrum graph would show spikes above the wavelengths representing the colors red and blue.
Famous quotes containing the word action:
“Let him [the President] once win the admiration and confidence of the country, and no other single force can withstand him, no combination of forces will easily overpower him.... If he rightly interpret the national thought and boldly insist upon it, he is irresistible; and the country never feels the zest of action so much as when the President is of such insight and caliber.”
—Woodrow Wilson (1856–1924)
