Part I of this review highlights key historical high points of the research odyssey that cracked the longevity code and provides the reader with a backstage pass to meet the enzymes encoded by SIRT1âthe seven nutrient-responsive NAD+-dependent histone deacetylase enzymes, dubbed the sirtuins.
To calculate the wavelength of a radio wave, you will be using the equation: Speed of a wave = wavelength X frequency. Since radio waves are electromagnetic waves and travel at 2.997 X 10^8 meters/second, then you will need to know the frequency of the radio wave. If the radio wave is on an FM station, these are in Megahertz.
Then, substitute into Î»Î½ = c: (4.88 x 10Â¯ 7 m) (x) = 3.00 x 10 8 m sÂ¯ 1. x = 6.15 x 10 14 sÂ¯ 1. The use of nm for wavelength is quite common. Problem #2a: Calculate the frequency of electromagnetic radiation that has a wavelength of 1.315 micrometers.hen, substitute into Î»Î½ = c: (4.88 x 10Â¯ 7 m) (x) = 3.00 x 10 8 m sÂ¯ 1. x = 6.15 x 10 14 sÂ¯ 1.
