âJoseph Ally, Shingle Springs, CA. A. Avocado oil is a fine choice for a healthful vegetable oil (itâs high in monounsaturated fats), but itâs probably not readily available in most supermarkets. In fact, most liquid vegetable oils are healthy choices, but someâprimarily olive and canolaâare healthier than others. Check our report on the extra-virgin olive oils, in which we found that some oils don't make the grade. And find out how to save at the supermarket on oils and other food items.
Light moves even faster AND has shorter wavelengths. These combine to give light extremely high frequencies. Red light has a wavelength of about 682 nanometers. Its frequency is around 440 terahertz.That's 440,000,000,000,000 hertz.ight moves even faster AND has shorter wavelengths. These combine to give light extremely high frequencies. Red light has a wavelength of about 682 nanometers. Its frequency is around 440 terahertz.
Therefore, higher is the frequency, higher would be the energy and longer is the wavelength, lower would be the energy. As we move from cosmic radiations to ultraviolet region to infrared. region and then radio frequencies, we are gradually moving to regions of lower energies.
