Vedclass · Answer

(D) The production mechanisms for electromagnetic waves are as follows:$1$. Microwaves are produced by electronic devices like Klystron valves or magnetron valves $(A-IV)$.$2$. Visible light is produced by the transition of electrons in atoms from a higher energy level to a lower energy level $(B-I)$.$3$. Gamma rays are high-energy electromagnetic radiations produced during the radioactive decay of atomic nuclei $(C-II)$.$4$. Infra-red rays are produced by the vibration of atoms and molecules $(D-III)$.Therefore, the correct matching is $A-IV, B-I, C-II, D-III$.

List-$I$ (Electromagnetic wave)	List-$II$ (Production)
$A$. Microwave	$I$. Electrons in atoms emit light when they move from a higher energy level to a lower energy level
$B$. Visible light	$II$. Radioactive decay of nucleus
$C$. Gamma rays	$III$. Vibration of atoms and molecules
$D$. Infra-red rays	$IV$. Klystron valve or magnetron valve
