# Is long wave electromagnetic radiation hot? If so, why?

Both infrared radiation and microwaves warms up objects it meets, so therefore I wonder, is all long wave electromagnetic radiation hot?

And if it is, why?

• What do you want to mean by saying that the radiation is "hot"? It heats up most successful of bodies as bodies and even the earth'and atmosphere is heated by long wave radiations. They are more absorbed than reflected. – Wrichik Basu May 14 '17 at 21:37
