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.
Tech Talk: Radio Waves in Astronomy. Radio waves are electromagnetic waves (light) with wavelengths between 1 millimeter (one thousandth of a meter) and 100 kilometers (one kilometer is equal to one thousand meters). In terms of frequency, this is equivalent to 300 Gigahertz (one Gigahertz is equal to one billion Hertz) and 3 kilohertz.
