Question

An electron falls from the conduction band of silicon (Si) to the valence band. The band gap of Si is 1.1 eV. What is the wavelength of the photon emitted by this process? Give your answer in nm.

Answer 1

plzzzz answer...

Answer 2

\[(6.6*10^-34)(3*10^8)/(1.1*1.6*10^-19)\]
\[1.125*10^-6m\]
but we have to answer in nm so it would be \[1125nm\]

Answer 3

1129 is the correct answer.Watch lecture video L15-4_100 again.
