A hydrogen atom initially in its ground state i.e., n= 1 level, absorbs a photon and ends up in n= 3 level. What must have been the frequency of the incident photon? (b) Now the electron makes spontaneous emission and comes back to the ground state. What are the possible frequencies of the photons emitted during this process?

What is wavelength of a photon that would be emitted when a hydrogen atom makes a transition from the n = 3 to the n = 2 energy level? What is the longest wavelength photon that could ionize a hydrogen atom originally in its ground state? What processes might occur if an electron of energy 12.2 eV collides with a hydrogen atom at rest and in its ground state?

This question has multiple parts. Work all the parts to get the most points. The energy of a photon needed to cause ejection of an electron from a photoemissive metal is expressed as the sum of the binding energy of the electron plus the kinetic energy of the emitted electron. When photons of 4.40x107m light strike a calcium metal surface, electrons are ejected with a kinetic energy of 1.75x10-20 J. a Calculate the binding energy of the calcium electrons. b...
