Vedclass · Answer

(A) The visible light spectrum ranges from approximately $380 \, nm$ (violet) to $750 \, nm$ (red). The maximum wavelength $(\lambda_{max})$ in the visible spectrum is $750 \, nm$. The energy of a photon is given by $E = \frac{hc}{\lambda}$. Using $hc \approx 1240 \, eV \cdot nm$, we get: $E = \frac{1240 \, eV \cdot nm}{750 \, nm} \approx 1.65 \, eV$. Rounding to the nearest provided option, the value is $1.6 \, eV$.

The energy of a photon of visible light with the maximum wavelength in $eV$ is approximately .......
