Plancks Quantum theory, Black body radiations

Question

Which graph shows how the energy E of a photon of light is related to its wavelength ($\mathrm{\lambda}$)?

Easy

Solution

The energy equation for a photon in term of wavelength ($\mathrm{\lambda}$) is given by

$\mathrm{E}=\frac{\mathrm{hc}}{\mathrm{\lambda}},\text{i.e.}\mathrm{E}\propto \frac{1}{\mathrm{\lambda}}$
