Cod liver oil - a potentially toxic source of Vitamin A: Hypervitaminosis A can result from ingestion of too much vitamin A from diet, supplements, or prescription medications.
This visible light region consists of a spectrum of wavelengths that range from approximately 700 nanometers (abbreviated nm) to approximately 400 nm. Expressed in more familiar units, the range of wavelengths extends from 7 x 10 -7 meter to 4 x 10 -7 meter.
(B) Light with a short wavelength has a high frequency and is high in energy. Visible light runs from approximately 400 nanometers to 700 nanometers, with red light corresponding to the 700 nm end and violet light corresponding to the 400 nm end.olour doesn't affect the energy of any lifeform in particular, but of the different visible colours of light, red has the least energy and violet has the most. some_blk Â· 8 years ago.
