Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound responsible for light absorption and the color of plants, chlorophyll, strongly absorbs light with a wavelength of 662.nm. Calculate the frequency of this light. Be sure your answer has the correct number of significant digits. | THz
