Problem

A photon traveling through fused silica (index of refraction

n = 1.46

) has an energy of 2.50 eV. Determine the wavelength of this photon while it is inside the fused silica, expressing your answer in nanometres. Use

c = 3.00 \times 10^{8}\,\text{m s}^{-1}

h = 6.626 \times 10^{-34}\,\text{J s}

, and

1\,\text{eV} = 1.602 \times 10^{-19}\,\text{J}
