Vedclass · Answer

(A) The energy of radiation is given by $E = h
u = \frac{hc}{\lambda}$.For option $A$: $\lambda = 300 \, pm = 3 	imes 10^{-10} \, m$. Thus,$E_A = \frac{hc}{3 	imes 10^{-10}} = h 	imes (3 	imes 10^8) / (3 	imes 10^{-10}) = h 	imes 10^{18} \, J$.For option $B$: $\lambda = 30 \, nm = 3 	imes 10^{-8} \, m$. Thus,$E_B = \frac{hc}{3 	imes 10^{-8}} = h 	imes (3 	imes 10^8) / (3 	imes 10^{-8}) = h 	imes 10^{16} \, J$.For option $C$: $
u = 3 	imes 10^{12} \, s^{-1}$. Thus,$E_C = h 	imes 3 	imes 10^{12} \, J$.For option $D$: $
u = 3 	imes 10^{10} \, s^{-1}$. Thus,$E_D = h 	imes 3 	imes 10^{10} \, J$.Comparing the values,$E_A = h 	imes 10^{18}$ is the highest energy.
