The energy of a photon of wavelength $λ$ is |
$hcλ$ $\frac{hc}{λ}$ $\frac{hλ}{c}$ $\frac{λ}{hc}$ |
$\frac{hc}{λ}$ |
The correct answer is Option (2) → $\frac{hc}{λ}$ The energy of a photon is given by: $E = h\nu$ where $h$ is Planck's constant and $\nu$ is the frequency of light. Since, $\nu = \frac{c}{\lambda}$, $E = h \frac{c}{\lambda}$ ∴ Energy of a photon: $E = \frac{hc}{\lambda}$ |
