Which type of radiation has the highest energy in the electromagnetic spectrum?

Gamma rays have the highest energy within the electromagnetic spectrum. This is primarily due to their very short wavelength and high frequency, which correlate directly to energy according to the formula (E = hf), where (E) is energy, (h) is Planck's constant, and (f) is the frequency of the radiation. As frequency increases, energy also increases, meaning that gamma rays, which have the highest frequencies, carry more energy than any other type of radiation in the spectrum.

In contrast, other types of radiation like X-rays and ultraviolet rays have longer wavelengths and lower frequencies than gamma rays, resulting in lower energy levels. Visible light, which is what our eyes can detect, falls even further down the spectrum with much longer wavelengths and lower frequencies compared to gamma rays, hence having significantly lower energy. Thus, gamma rays stand out as the most energetic type of radiation, serving a crucial role in areas such as medical imaging and treatments, as well as in understanding cosmic phenomena.
