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.
First, the radio station encodes some information on a radio wave. This is known as modulation. They then broadcast the radio wave with the encoded information onto a certain frequency. Your radio antenna picks up the broadcast based on the frequency to which your radio dial is tuned. Your radio then decodes the information from the radio wave and plays that information through the speakers as sound.
