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