1. Definition of Frequency
Frequency refers to the number of occurrences of a repeating event per unit of time. It is commonly expressed in hertz (Hz), where one hertz is equal to one cycle per second. Understanding frequency is essential in various scientific and engineering disciplines, as it helps quantify how often an event occurs.
2. Units of Frequency Measurement
Frequency can be measured in various units, depending on the context and the scale of the phenomena being studied. Below are some of the most commonly used units:
2.1 Hertz (Hz)
The hertz (Hz) is the standard unit of frequency in the International System of Units (SI). One hertz is defined as one cycle per second. This unit is widely used in physics and engineering to describe various phenomena, such as sound waves and electrical signals.
2.2 Kilohertz (kHz)
A kilohertz (kHz) is equal to 1,000 hertz. This unit is commonly used to measure audio frequencies. For example, human hearing typically ranges from 20 Hz to 20 kHz.
2.3 Megahertz (MHz)
A megahertz (MHz) is equal to one million hertz. This unit is often used in telecommunications, particularly in radio frequency applications. For instance, FM radio stations broadcast in the MHz range.
2.4 Gigahertz (GHz)
A gigahertz (GHz) is equal to one billion hertz. This unit is commonly used in the context of computer processors and microwave communications, where high-frequency signals are essential for performance.
