Do LASER beams have a higher or lower frequency compared to radio waves?

LASER beams indeed have a higher frequency compared to radio waves. This is primarily due to the electromagnetic spectrum, where different types of electromagnetic radiation are categorized based on their wavelength and frequency.

Radio waves occupy a lower frequency range on the electromagnetic spectrum, generally from about 3 kHz to 300 GHz. In contrast, LASER beams, which emit light in the visible or near-visible spectrum, can have frequencies on the order of hundreds of terahertz (THz). Specifically, wavelengths in the visible spectrum correspond to frequencies that are much higher than those of radio waves.

As the frequency of electromagnetic waves is inversely proportional to their wavelength (where shorter wavelengths correspond to higher frequencies), LASER beams, which typically have much shorter wavelengths than radio waves, thus exhibit substantially higher frequencies. This fundamental property is crucial in various applications of LASER technology, where precise control over the frequency and wavelength allows for applications such as optical communications, medical technologies, and precision measurements.
