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.
We can calculate the wavelength of sound waves that we can hear using the formula wavelength = velocity / frequency. In air sound travels at about 340 meters per second (the precise value depends on temperature, humidity, and pressure). We hear (measured in air) range from about two-thirds of an inch to 50 feet.
