The energy gap for silicon at 300 k is 1.14 ev. (a) find the lowest frequency photon that will promote an electron in silicon from the valence band to the conduction band.

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
