Ultraviolet radiation has the shortest wavelength. Gamma rays have the highest energy per photon. Electromagnetic radiation interacts with matter and blackbody is an important concept.
Ultraviolet radiation has the shortest wavelength among the listed types of electromagnetic radiation. Wavelengths decrease from radio waves to gamma rays, with ultraviolet having a shorter wavelength than visible, infrared, and radio waves.
The ranking of electromagnetic radiation by energy per photon is: gamma, X-ray, ultraviolet, visible, infrared, microwave, and radio. Gamma rays have the highest energy per photon.
Electromagnetic radiation interacts with matter through processes like absorption, reflection, and transmission. A blackbody is an idealized physical body that absorbs all incident electromagnetic radiation.
