Frequency

Number of oscillations in a time unit. Frequency and wavelength are connected to each other.

The measure of frequency is Hertz (Hz):
1 Hz = 1 oscillation per second = 1/s.
1 kilohertz (kHz) = 1000 Hz
1 megahertz (MHz) = 1000 kHz
1 gigahertz (GHz) = 1000 MHz
1 terahertz (THz) = 1000 GHz

On April 25th, 2017 the operating duties and responsibilities for the Morsleben repository were transferred to the BGE, the Federal Company for Radioactive Waste Disposal. Therefore this archival page of the Federal Office for Radiation Protection has not been updated since April 24th, 2017.
