LIGHT: African violets are grown indoors. They like bright, but filtered, sunlight. Do not place in direct sun. They can also be grown under florescent lights. The lights are usually suspended 12 to 18 inches above the violet for 8 to 14 hours a day.
I remember it as the highest frequency indicating the highest energy. The higher the frequency, the faster the oscillations and thus the higher the energy. Therefore, the highest-frequency ultra-violet light (or the lowest wavelength) is violet. However, the highest-frequency visible light would have to be roughly blue.
