The microwave spectrum typically ranges from?

The microwave spectrum is typically understood to encompass frequencies ranging from 300 MHz to 300 GHz. This range is significant within the electromagnetic spectrum and is vital for various applications, including telecommunications, radar, and microwave ovens. The designation of microwaves in this frequency range is due to their ability to penetrate many materials and their suitability for transferring energy.

This range includes several subcategories, such as L-band, S-band, C-band, X-band, K-band, and others, which are utilized in different technologies and industries. Understanding that microwaves operate at frequencies above radio waves (which would include the lower ranges) yet below infrared radiation clarifies their position in the electromagnetic spectrum. This recognized range of frequencies is fundamental to fields like industrial hygiene, where knowledge of microwave radiation exposure and safety standards is essential.
