Vedclass · Answer

(A) The electromagnetic spectrum classifies waves based on their wavelength or frequency. Infrared rays have wavelengths ranging from approximately $1 \, mm$ to $700 \, nm$ ($10^{-3} \, m$ to $7 	imes 10^{-7} \, m$). Converting these values to centimeters $(1 \, m = 100 \, cm)$: $10^{-3} \, m = 10^{-1} \, cm$ $7 	imes 10^{-7} \, m = 7 	imes 10^{-5} \, cm$. Comparing the given options,$10^{-4} \, cm$ falls within the infrared wavelength range,while the other values are closer to or within the visible and ultraviolet regions. Therefore,the correct option is $A$.

Which of the following represents the wavelength range of infrared rays?
