Vedclass · Answer

(D) The wavelength ranges for the given electromagnetic radiations are as follows:$(a)$ Microwave: The wavelength is approximately $10^{-3} \, m$ to $0.3 \, m$. Thus, $(a) \rightarrow (iv)$.$(b)$ Gamma rays: These have the shortest wavelengths, typically less than $10^{-13} \, m$ (often cited as $10^{-15} \, m$ in this context). Thus, $(b) \rightarrow (ii)$.$(c)$ $A.M.$ radio waves: These have very long wavelengths, typically in the range of $100 \, m$ to $1000 \, m$. Thus, $(c) \rightarrow (i)$.$(d)$ $X$-rays: These have wavelengths in the range of $10^{-8} \, m$ to $10^{-12} \, m$ (often cited as $10^{-10} \, m$). Thus, $(d) \rightarrow (iii)$.Therefore, the correct matching is $(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)$.

The correct match between the entries in column $I$ and column $II$ is:
$I$ (Radiation) | $II$ (Wavelength)
$(a)$ Microwave | $(i)$ $100 \, m$
$(b)$ Gamma rays | $(ii)$ $10^{-15} \, m$
$(c)$ $A.M.$ radio waves | $(iii)$ $10^{-10} \, m$
$(d)$ $X$-rays | $(iv)$ $10^{-3} \, m$
