1. (a) Describe the photoelectric effect with the aid of a clearly labeled diagram showing an apparatus. (b) Derive an equation from conservation of energy for the stopping potential in terms of the frequency of the incident light and the work function for the material. Define variables used. (c) Describe an observation for the photoelectric effect that can’t be explained using classical physics. (1 mark) (d) The work function for a certain metal is 1.8 eV. What is the stopping potential for ejected electrons when light of wavelength 400 nm shines on the metal? (e) An orbiting satellite can become charged by sunlight via the photoelectric effect. This can affect sensitive electronics, and to minimize this a satellite is coated with platinum, which has a large work function, ? = 5.32 eV. What is the longest wavelength of incident sunlight that can charge the satellite?

1.With the aid of a labeled diagram, describe the Bohr model of
the hydrogen atom.
2. Derive the following relationship for a hydrogen atom
according to the Bohr model: rn = a n 2 where rn are the permitted
radii of the electron orbit, n = 1, 2, 3…, and ‘a’ is a constant.
Determine ‘a’ in terms of variables that you define. Hint: equate
Coulomb’s law with the centripetal force acting on an electron, and
then take angular momentum...
