The photoelectric effect in a cosmic context. Ultraviolet radiation striking dust grains composed of the moon’s dominant rock type, feldspar (with work function 4.5 eV), leaves them with a small electric charge. Smaller grains levitate due to the resulting electrostatic repulsion, giving the surface a diffuse dust halo. 200 nm ultraviolet strikes a dust grain and ejects an electron.What is the electron’s kinetic energy?A. 1.7 eV           B. 4.5 eVC. 6.2 eV           D. 10.7 eV
Just like the optical part of the spectrum, radio waves can be described in terms of photons - although they can be very difficult to detect. Consider the photons in radio waves from an FM station that has a 88.5-MHz broadcast frequency. A.   Find the energy, in joules, of a photon in the radio waves.  B.  Find the energy, in electron volts, of a photon in the radio waves.
Consider a model of an electron as a hollow sphere with radius R and the electron charge -e spread uniformly over that surface. d. Use Einstein’s equation relating rest mass to energy to derive a value for R. Unfortunately, your answer will be model-dependent. The traditional “Classical radius of the electron” is derived by setting the electrostatic work to be e2/(4pi e0 R)
