3.12 Properties of Photons
A student uses a spectrometer to test a blue LED used in a fluorescence sensor. The maximum emission from the LED occurs at a wavelength of \(4.50 \times 10^2 \text{ nm}\). Use \(h=6.63\times10^{-34}\text{ J s}\) and \(c=3.00\times10^8\text{ m/s}\).
What is the energy of a single photon emitted by the LED?
