Vedclass · Answer

(A) The electromagnetic spectrum is categorized by wavelength ranges:$1$. Radio waves have long wavelengths,typically $10^3 \ m$ to $10^{-1} \ m$ (or higher,up to $10^7 \ m$ for long-wave radio).$2$. $X$-rays have very short wavelengths,typically in the range of $10^{-8} \ m$ to $10^{-12} \ m$. Thus,$10^{-10} \ m$ corresponds to $X$-rays.$3$. Visible light has wavelengths in the range of approximately $4 	imes 10^{-7} \ m$ to $7 	imes 10^{-7} \ m$. Thus,$10^{-7} \ m$ (or $100 \ nm$) is close to the ultraviolet/visible boundary,but in the context of standard multiple-choice options,it is categorized as visible light.Therefore,$10^7 \ m$ is a Radio wave,$10^{-10} \ m$ is an $X$-ray,and $10^{-7} \ m$ is Visible light.
