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.
Radio Telescope: Radio telescope is an astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation emitted by extraterrestrial sources. Because radio wavelengths are much longer than those of visible light, radio telescopes must be very large in order to attain the resolution of optical telescopes.
