Problem

A photon carries an energy of

3.10\,\text{eV}

. What is its wavelength? Constants:

h = 6.63\times10^{-34}\,\text{J\,s}

c = 3.00\times10^{8}\,\text{m/s}

1\,\text{eV} = 1.60\times10^{-19}\,\text{J}

. a)

2.49\times10^{-7}\,\text{m}

4.00\times10^{-7}\,\text{m}

6.40\times10^{-7}\,\text{m}

1.34\times10^{-6}\,\text{m}
