What is the wavelength of an electron with a kinetic energy of 8 keV? What are the wavelength and frequency of the 8 keV x-rays frequently used for protein crystallography experiments? Compare to question 17 (What is the wavelength of an electron with a kinetic energy of 8 keV?). Consider electrons are accelerated with 5 kV voltage in a cathode ray tube. What is the short wavelength limit (SWL) of the continuous radiation that will be obtained? Thanks

In a laboratory experiment, an electron with a kinetic energy of 0.440 keV is shot toward another electron initially at rest (see figure below). (1 eV = 1.602 ✕ 10−19 J) The collision is elastic. The initially moving electron is deflected by the collision. (a) Is it possible for the initially stationary electron to remain at rest after the collision? Yes. However, this will only occur when the moving electron has a much higher kinetic energy than the question states....

In the figure, an electron with an initial kinetic energy of 4.00 keV enters region 1 at time t = 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.00510 T. The electron goes through a half-circle and then exits region 1, headed toward region 2 across a gap of 25.0 cm. There is an electric potential difference ΔV = 2000 V across the gap, with a polarity such that the electron's speed increases uniformly...
