To four significant figures, a) what is the energy of a photon emitted from a hydrogen atom when an electron makes a transition from n=6 to n=2
b) find the energy of electromagnetic radiation necessary for ionization (transition to n=invinity) of the 1s1 electron in a hydrogen atom?
Please help step by step so I can duplicate it.
Thank you
a.
Rydberg equation is
= RH × ( )
RH is Rydberg constant. h is planck constant , c is velocity of light.
ni =2
nf = 6
or, E = RH × h× c× ()
or, E = 1.09737 × 107 × 6.626×10-34 ×3×108 ×(2/9)
or, E = 4.847 ×10-19 J.
hence, energy of photon emitted = 4.847×10-19 J.
b.
ni = 1
nf = infinity
E = RH × C× h × ( )
or, E = 1.09737×107 ×6.626×10-34 × 3×108 ×1
or, E = 2.181×10-18 J.

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?
