 Frequency: The number of oscillations per second. We use the variable f for frequency. The unit for frequency is 1/seconds, which is called a hertz, named after the German physicist Heinrich Hertz. A hertz is shortened to Hz. Some other units that we use for frequency include a megahertz (1 MHz = 1 × 10⁶ Hz), a gigahertz (1 GHz = 1 × 10⁹ Hz), and a terahertz (1 THz = 1 × 10¹² Hz).
