Question

Match List - I (Experiment performed) with List - II (Phenomena discovered/ associated) and select the correct option from the options given below the lists :

	List - I		List - II
(a)	Davisson and Germer Experiment	(i)	Wave nature of electrons
(b)	Millikan's oil drop experiment	(ii)	Charge of an electron
(c)	Rutherford experiment	(iii)	Quantisation of energy levels
(d)	Franck - Hertz experiment	(iv)	Existence of nucleus

• A. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
• B. (a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)
• C. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
• D. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

Answer 1

Answer: (B)

(a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)

Davisson and Germer Experiment$\Rightarrow$Wave nature of electrons
Millikan's oil drop experiment$\Rightarrow$Charge of an electron
Rutherford experiment$\Rightarrow$Existence of nucleus
Franck - Hertz experiment$\Rightarrow$Quantisation of energy levels .
