Physics 2102. Gabriela Gonz. á. lez. Michelson interferometers:. As we saw in the previous example, interference is a spectacular way of measuring small distances (like the thickness of a soap bubble), since we are able to resolve distances of the order of the wavelength of the light (for instance, for yellow light, we are talking about 0.5 of a millionth of a meter, 500nm). This has therefore technological applications.. One Photon at a Time. By:. Kevin Masson. I then found positions of the slit blocker that would effect the double slit, there are five positions;.
