(a) Draw a picture to represent the set up and note where the path length differences comes from in a Michelson Interferometer. (b) A Michelson Interferometer with a He-Ne laser light source ( = 550nm) projects its interference pattern on a screen. If the movable mirror is caused to move by 4.95m, how many fringes will be observed shifting through a reference point on a screen? (c) In a Michelson Interferometer, when the movable mirror is moved by exactly 0.1mm, the number of fringes observed moving through is 316. What is the wavelength of the light?
