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.
1 1.0 nanosecond â cycle time for radio frequency 1 GHz (1 Ã 10 hertz), an inverse unit. 2  This corresponds to a radio wavelength of 1 light-nanosecond or 0.3 m, as can be calculated by multiplying 1 ns by the speed of light (approximately 3 Ã 10 m/s) to determine the distance traveled. 1.0 nanosecond â cycle time for radio frequency 1 GHz (1 Ã 10 hertz), an inverse unit. 2  This corresponds to a radio wavelength of 1 light-nanosecond or 0.3 m, as can be calculated by multiplying 1 ns by the speed of light (approximately 3 Ã 10 m/s) to determine the distance traveled.
