What is the order of the electromagnetic spectrum from highest frequency to lowest frequency?

The order of the electromagnetic spectrum from highest frequency to lowest frequency begins with gamma rays, which have the highest energy and frequency. Following gamma rays are X-rays, which are also high-frequency waves but have slightly lower energy than gamma rays. Ultraviolet (UV) light comes next, as it carries more energy than visible light but less than X-rays.

Visible light follows UV in the spectrum and consists of the colors that the human eye can detect. Beyond visible light, infrared (IR) radiation has a lower frequency, followed by microwaves, which have even lower frequencies. Finally, radio waves occupy the lowest frequency end of the spectrum, characterized by the longest wavelengths.

This sequence is a fundamental aspect of electromagnetic radiation, illustrating the relationship between frequency and energy, with higher frequencies correlating to greater energy and shorter wavelengths. The chosen answer precisely captures this order, reinforcing the understanding of the electromagnetic spectrum.
