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.

Report Abuse. False. Light travels at the same speed regardless of the wavelength. Longer wavelengths mean that it takes longer for the entire wave to pass a single point than it takes for a shorter wavelength to pass a single point, since the light travels at the same speed.ess waves per second mean a lower frequency of waves per second. So, longer wavelengths have a lower frequency than shorter wavelengths. But, they both travel at the exact same speed. .
