I’ve often heard that Infrared rays are called “heat rays”. However, I feel like this term is a misnomer. Don’t all the wavelengths of electromagnetic radiation carry energy?
Judging by how gamma rays are highly penetrating and are dangerous when absorbed by tissues, radiations of lower wavelengths should carry more energy, and should be able to increase the internal energy of the object that absorbed it much more than infrared rays can. This seems consistent with the conservation of energy for an isolated system:
where TERTER stands for transfer of energy by electromagnetic radiation
Then why are UV rays, X-rays and gamma rays not classified as “heat rays”.
