A megahertz is one million (or 10⁶) hertz. See hertz, kilohertz ( one thousand hertz), gigahertzA gigahertz is a billion hertz or a thousand megahertz, a measure of frequency. Each cycle is one nanosecond. Radio waves sent at gigahertz frequencies usually travel in line of sight. Gigahertz frequencies or microwaves are also used in cellular telephon (10⁹ hertz), terahertzA terahertz is 1012 hertz or a thousand gigahertz, a measure of frequency. At one terahertz, each cycle is one picosecond, and the wavelength in free space is roughly 300 μm. Radio waves sent at terahertz frequencies usually travel in line of sight. (10¹² hertz), and petahertzA petahertz is a measure of frequency equal to a quadrillion hertz or a thousand terahertz. In the electromagnetic spectrum, the low end of the petahertz range includes ultraviolet light, visible light, and infrared light, while the upper range includes X (10¹⁵ hertz).
