Vedclass · Answer

(A) The infrared region of the electromagnetic spectrum extends from the red edge of the visible spectrum ($700 \ nm$ or $7 	imes 10^{-5} \ cm$) to $1 \ mm$ $(0.1 \ cm)$.Converting the options to centimeters:$A) 10^{-4} \ cm = 1000 \ nm$$B) 10^{-5} \ cm = 100 \ nm$$C) 10^{-6} \ cm = 10 \ nm$$D) 10^{-7} \ cm = 1 \ nm$Since $10^{-4} \ cm$ falls within the range of $7 	imes 10^{-5} \ cm$ to $0.1 \ cm$,option $A$ is the correct representation of an infrared wavelength.
