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.
A radio wave is described by its wavelength, the distance from one crest to the next, or its frequency, the number of crests that move past a point in one second. Wavelengths of radio waves range from 100,000 m (270,000 ft) to 1 mm (.004 in). Frequencies range from 3 kilohertz to 300 gigahertz.
