- Why does the energy of characteristic x rays become increasingly greater for heavier atoms?X-rays have a wavelength of 0.71 A)) scattered by a piece of carbon at a right angle, then analyzed by a spectrometer, the kinetic energy of the returning electron is: - 772 ev -672 ev - 872 ev - 572 evWhat is the longest wavelength (in m} of the EM radiation that can eject photoelectrons from a certain metal target, given that the binding energy is 6.81 eV? Exponential format with 3 SF.
- Calculate the resonance frequency and the corresponding wavelength for an electron in a magnetic field of 0.330 T, the magnetic field commonly used in EPR.If an alpha particle has 50 fm as its distance of closest approach when incident on a gold foil, what will be its kinetic energy?Whilst the vast majority of alpha particles passed through the gold foil with little or no deviation, a small fraction of them were scattered through larger angles, some even backwards. Commenting on these findings Rutherford wrote “It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.” Explain the implications of Rutherford’s results for models of atomic structure
- What is the maximum kinetic energy in eV of electrons ejected from a certain metal by 500 nm EM radiation, given the binding energy is 2.20 eV? eVWhat is the Compton scattering angle for gamma rays which have awavelength of 10.00 pm after scattering, 9.67 pm before?If an alpha particle has 20 fm as its distance of closest approach when incident on a gold foil, what will be its kinetic energy?
