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 The number of waves of. 2  of a particular wavelength passing a fixed point per second. 3  The unit of frequency is the Hertz, one per second. 4  The frequency of a signal multiplied by its wavelength equals its velocity, so that electromagnetic radiation of one metre wavelength must have a frequency of 300,000,000.
