Homework Statement
Suppose that a beam of light consists of photons having an energy of 5.4 eV. what is the wavelength of the light?
Homework Equations
hc = 1240 eV*nm
[tex] E = \frac{hc}{\lambda} [/tex]
The Attempt at a Solution
[tex]5.4eV = \frac{1240eV*nm}{\lambda}[/tex]
[tex]\lambda = \frac{1240ev*nm}{5.4eV}[/tex]
[tex]\lambda = 229.630 nm[/tex]
