Two lasers have identical wavelengths, 632.8 nm. One laser is fixed while the other laser can be moved forward and backwards. Initially the two lasers start at the same location. (Assume this to be a 1D problem!) 1) Lasers must be used for this “experiment” works. What special property of laser light will allow this “experiment” to work? 2) How do the light waves interfere (constructively, destructively, somewhere in between)? 3) How far (from the starting position in nm) should the second laser be moved forward to also have constructive interference?
