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.
