An electron accelerates through a twelve.five V potential contrast, starting from rest, and then crash with a hydrogen atom, exciting the atom to the highest energy level grant. List all the probable quantum-jump progression by which the excited atom could emit a photon and the wavelength of each.
Answer: ribosomes and membranes.
Explanation:
Use the formula E=hv, h=plancks constant and v=frequency
use the formula c=v*lambda to find v
the answer will be 2.88*10^-23J
