Vedclass · Answer

(C) The energy of a photon is given by the formula $E = \frac{hc}{\lambda}$.Using the shortcut formula $E(	ext{eV}) = \frac{12400}{\lambda(\mathring{A})}$,we get:$E = \frac{12400}{1000} \, 	ext{eV} = 12.4 \, 	ext{eV}$.To convert this energy into Joules,we multiply by the charge of an electron $(1.6 	imes 10^{-19} \, 	ext{C})$:$E = 12.4 	imes 1.6 	imes 10^{-19} \, 	ext{J}$.$E = 19.84 	imes 10^{-19} \, 	ext{J}$.

Calculate the energy of a photon having wavelength $\lambda = 1000 \, \mathring{A}$ in Joules.
