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.
Wavelength is a measure of the distance between two crests or two troughs of a wave. The greater the wavelength, the more energy a wave has. AM radio stations have a big wavelength. You might have tuned the radio dial at night and heard stations that were far away and unable to be heard during the daytime.
