Question 27: EM waves

Question

Match List I (Wavelength range of electromagnetic spectrum) with List II.  (Method of production of these waves) and select the correct option from the options given below the lists.

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).
