Infinity Learn · Accepted Answer

EM waves having wave length 700nm to 1mm relates to Vibration of atoms and molecules.

EM waves having wave length 1nm to 400nm relates to inner shell electrons in atoms moving one energy to lower level.

EM waves having wave length $< 10^{- 3} n m$ relates to radio active decay.

EM waves having wave length $1 m m$ to $0.1 m$ relates to magnetron valve. It produces microwaves.
