Question:

The correct match between the entries in column I and column II are :

  1. (1) (A)-(ii), (B)-(i), (C)-(iv), (D)-(iii)

  2. (2) (A)-(i), (B)-(iii), (C)-(iv), (D)-(ii)

  3. (3) (A)-(iii), (B)-(ii), (C)-(i), (D)-(iv)

  4. (4) (A)-(iv), (B)-(ii), (C)-(i), (D)-(iii)


Correct Option: , 4

Solution:

(4) Energy sequence of radiations is

$E_{\gamma \text {-Rays }}>E_{\text {X-Rays }}>E_{\text {microwave }}>E_{\text {AM Radiowaves }}$

$\therefore \lambda_{\gamma \text {-Rays }}<\lambda_{X \text {-Rays }}<\lambda_{\text {microwave }}<\lambda_{A M}$ Radiowaves

From the above sequence, we have

(1) Microwave $\rightarrow 10^{-3} \mathrm{~m}$ (iv)

(2) Gamma Rays $\rightarrow 10^{-15} \mathrm{~m}$ (ii)

(3) AM Radio wave $\rightarrow 100 \mathrm{~m}$ (i)

(4) X-Rays $\rightarrow 10^{-10} \mathrm{~m}$ (iii)
