Question

1 a) For the red wavelength in slide 11 in the photons notes, show whether the wavelengths and energies given are consistent b) For the blue light, the energy of the photon absorbed is larger than the energy needed to free an electron from the surface. Where does the additional energy go?

Step 1

Red light typically has a wavelength range of approximately 620-750 nanometers (nm) and an energy range of approximately 1.65-1.99 electron volts (eV). If the wavelengths and energies given in the slide fall within these ranges, then they are consistent with red Show more…
