Problem

In a semiconductor experiment, a photon with an energy of

3.40\times10^{-19}\,\text{J}

is absorbed by the material. Assume the photon travels through vacuum before absorption. Use the following constants as needed: • speed of light in vacuum:

3.00\times10^{8}\,\text{m}\,\text{s}^{-1}

• Planck constant:

6.626\times10^{-34}\,\text{J}\,\text{s}

a) Calculate the frequency of the photon. b) Determine the wavelength of this photon in nanometres (nm).
