Vedclass · Answer

(B) The electromagnetic spectrum in increasing order of wavelength is: Gamma rays $1$. Radioactive source produces Gamma rays $(\lambda \approx 10^{-12} 	ext{ m})$.$2$. $X$-ray tube produces $X$-rays $(\lambda \approx 10^{-10} 	ext{ m})$.$3$. Sodium lamp produces Visible light $(\lambda \approx 10^{-7} 	ext{ m})$.$4$. Magnetron valve produces Microwaves $(\lambda \approx 10^{-3} 	ext{ m})$.Therefore, the correct sequence in increasing order of wavelength is: Radioactive source $ightarrow$ $X$-ray tube $ightarrow$ Sodium lamp $ightarrow$ Magnetron valve.

List-$I$ (Electromagnetic waves)	List-$II$ (Use)
$(a)$ $UV$ rays	$(i)$ Diagnostic tool in medicine
$(b)$ $X-$rays	$(ii)$ Water purification
$(c)$ Microwave	$(iii)$ Communication,Radar
$(d)$ Infrared wave	$(iv)$ Improving visibility in foggy days

Choose the correct sequence of the radiation sources in increasing order of the wavelength of electromagnetic waves produced by them.
