In the photoelectric-effect experiment, as illustrated by the figure, a current is measured while light is shining on the cathode. But this does not appear to be a complete circuit, so how can there be a current? Explain.
When the police use a radar gun to measure a car's speed, photons are fired at the car. The photons hit the car and bounce back to the radar gun. If you got a speeding ticket, could you use Heisenberg's uncertainty principle in your defence? Explain briefly.
I am struggling with getting this question done and need some help solving it, explain and make sure the answer is 100% correct.
When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced; the electron slows down. In the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E� of a photon of radiated light:
Eγ=K−K′��=�−�′,
where K� and K′�′ are the kinetic energies of the electron before and after radiation, respectively.
This kind of radiation is called bremsstrahlung radiation, which in German means "braking radiation" or "deceleration radiation." The highest energy of a radiated photon corresponds to the moment when the electron is completely stopped.
