Suppose a uniformly charged (with a linear charge density) wire starts at point 0 and rises vertically along the positive axis to a length. Determine the x-component of the electric field at point. That is, compute near one end of a long wire, in the..
Consider the Compton Effect. We direct an x-ray beam into some material. The wavelength of the x rays is 0.1532 nm. Find the wavelength (nm) of the x rays which are scattered back toward the source (λ = 180 degrees). Give the answer to four signific..
