Problem

Assume the speed of light in vacuum is

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

. What is the frequency of ultraviolet radiation that has a wavelength of

250\,\text{nm}

in vacuum? a)

7.50\times10^{14}\,\text{Hz}

1.20\times10^{15}\,\text{Hz}

1.20\times10^{14}\,\text{Hz}

1.50\times10^{15}\,\text{Hz}
