Accepted Answer

Based on the given information, let's match the items from List I with their corresponding descriptions in List II :
(a) Range : 700 nm to 1 mm
Match : (i) Vibration of atoms and molecules
(b) Range : 1 nm to 400 nm
Match : (ii) Inner shell electrons in atoms moving from one energy level to a lower level
(c) Range : <10
-3
nm
Match : (iii) Radioactive decay of the nucleus
(d) Range : 1 mm to 0.1 m
Match : (iv) Magnetron valve
Therefore, the correct matches are :
(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv).
