02 Transverse Doppler Effect
Today, I would like to introduce a way to check relativistic effects in a narrow laboratory. Relativistic effects are usually hard to see in the lab. It is difficult because it requires an incredibly fast speed. But there is a way. Initially, experiments were conducted using excited hydrogen atoms. What we are going to do today is look at Walter Kündig's method. The basic method of Kündig is as follows. [Walter Kündig, “Measurement of the Transverse Doppler Effect in an Accelerated System”, Phys. Rev. 129, 2371(1963)] Walt K ü ndig 's Experimental Devices It uses a device that turns quickly like a centrifuge. It measures the frequency of light emitted from the source by placing the source in the middle and the absorber at the edge. The story of the experimental device is not important, but please read the literature if you are interested in learning about that. The e xperimental results are interesting...
