PHIL 311 Lecture 12: October 10, 2019

In order to show the isotropy and homogeneity of space-time and equivalence of different inertial frames , How do you transform the space time coordinates (x,y,z,t) in inertial frame K to (x',y',z',t') in inertial frame K' if K' moves in the positive x direction with speed v as seen from K . Use f,g, and h as functions of (v)x(v).

In each atom of a metal target in an X-ray tube, there are Z protons. This metal emits a K(sub alpha) X-ray that has a wavelength of 1.45 x 10^(-10)m. Use the Bohr model to estimate the K (sub alpha) X-ray wavelength emitted by a target each atom of which contains Z-1 protons.
