1. I have already read the method in which spectroscopy is performed. But I did not understand at all. If this method is accurate, how does it work?
2. Semiconductor band gap

1. Do you understand how the wavelength and energy of a photon are related?

2. Do you understand that an atoms electrons may only have specified energy levels, and that there are gaps between those energy levels?

Yes, I knew and of course, thank you for the reminder.
