Electromagnetic wavelength.

In the figure below, you can quickly compare the length and frequency of light or an electromagnetic wave and assess belonging to the wave range.

Relationship between the length of an electromagnetic wave (light) and frequency

The speed of light (electromagnetic wave) in vacuum = 299 792 458 (m/s), in our calculations we will take it as 300,000,000 (m/s).

The formula, calculator and graph below links the length of an electromagnetic wave (light) to frequency and allows you to find:
- The length of the electromagnetic wave through the frequency;
- Frequency through electromagnetic wavelength.

The electromagnetic wave is the main element in the technology of information transmission and communication. It is electromagnetic radiation that propagates in space without requiring any substance to do so. The length of an electromagnetic wave is one of its main parameters and is of great importance in various fields of science and technology.

The length of an electromagnetic wave is defined as the distance between two adjacent points on a wave that are in the same phase of oscillation. The unit of measure for wavelength is the meter (m). However, due to the fact that the electromagnetic wavelength can be very small, additional units of measurement are also used.

The length of an electromagnetic wave is directly related to its frequency. Frequency, in turn, determines the number of oscillations per unit time. The higher the frequency, the shorter the wavelength. For example, for radio waves, the length can be from several meters to several centimeters, and for visible light, from several hundred nanometers to several tens of nanometers.

The length of the electromagnetic wave is of great importance in various fields of science and technology. For example, in optics, wavelength is one of the factors that determines the color of light. In radio engineering, wavelength is used to transmit information over long distances. In medicine, the wavelength is used to diagnose and treat various diseases.

Also, the length of the electromagnetic wave is directly related to electromagnetic waves of various frequencies. For example, radio waves have lengths from a few centimeters to several meters, microwaves from a few millimeters to several centimeters, infrared rays from a few micrometers to several hundred micrometers, and ultraviolet rays from a few nanometers to several hundred nanometers.

In conclusion, the length of an electromagnetic wave is one of the main parameters that determine the properties of electromagnetic waves. It is of great importance in various fields of science and technology, and its study allows a deeper understanding of the laws of nature and the development of new technologies.
