1) A certain atom has an energy level of 2.58 eV above the ground level. Once excited to this level, the atom remains in this level for 1.64 10-7 s before emitting a photon and returning to the ground level.
a/ What is its wavelength? What is the color of this light?
b/ What is the smallest possible uncertainty in energy (in eV) of the photon?
2)Find the width L of a one-dimensional box that would correspond to the absolute value of the ground state of a hydrogen atom. What is your observation?
