Identical light beams (i.e. same intensity and wavelength) strike three different metals, all of which emit electrons.
Part A: Which metal results in the fastest ejected electrons?
A) Lead
B) Copper
C) Nickel
D) The maximum speed is the same for all metals
Part B: Which metal results in the least number of ejected electrons per second?
A) Copper
B) Nickel
C) Lead
D) The number of the ejected electrons is the same for all 3 metals
**Can you explain to me, in Part A, why Lead is the metal the results in the fastest ejected electrons? In Part B, why the number of ejected electrons is the same for all 3 metals? Thank you.
Please answer the following question :1. After being scattered by an electron, the wavelength of the x-ray changes in what way? Does that scattered x-ray gain or lose energy? Is this what classical electromagnetic theory predicts?
2. What would the shapes of the graphs be if the classical explanation was the correct explanation?
3. Examine the graph at the lower right. Are the deflected x-rays uniformly distributed over all the scattering angles? Does the shape of that distribution change for different incoming x-ray energies?
Part B: What is the energy of the system when in its excited state, in units of eV?
