I need to make sure my method and the formula I have used is correct. Also, my answer for the wavelength seems slightly dodgy.
An electron recombines with a hole losing 2.6eV of electrical potential energy. Calculate the wavelength of the light emitted.
Not given. Equations have to be used ourself.
[itex]E = \frac{hc}{\lambda}[/itex]
[itex]\lambda = \frac{hc}{E}[/itex]
[itex]\lambda = \frac{(6.63 \times 10^{-34})(3.00 \times 10^8)}{2.6}[/itex]
[itex]\lambda = 7.65 \times 10^{-26}m[/itex]
