PHY 252 Lab 2: Searching for the AEther Wind Fall 2009 In this lab, you will use the same Michelson interferometer setup from last week, but look at its measurement characteristics in more depth and then seek to look for the “AEther wind” which, if it existed, might have been expected to alter the speed of light. 1 Determining random and systematic errors Last week you noted a micrometer position in its dial units, which we will call d 1 . You then moved the micrometer until m fringes had crossed your reference mark on a viewing screen, at which point you recorded a second micrometer position d 2 . As we’ll see later on in the course, we can predict from fundamental physics the emission wavelength corresponding to a particular atomic transition, so we will assume that the wavelength λ of light emitted from the laser is a known quantity. Therefore, we can determine a scaling factor k between micrometer dial position differences ( d 2 - d 1 ) and true physical distances x 12 from x
