... the viewing axis about 25cm from the instrument. Two reflected images of the pointer should then be visible, and by adjusting the tilt controls on the mirror M1 those images can be superimposed. 3. By further adjustment, vertical straight fringes were produced with about nine of them in the field of ...

... At first, physicists were reluctant to accept the dual nature of light. After all, many of us humans like to have one right answer. But Einstein paved the way in 1905 by embracing wave-particle duality. We've already discussed the photoelectric effect, which led Einstein to describe light as a photo ...

It is also possible to tailor the waveguide contribution such that the total dispersion D is relatively small over a wide wavelength range extending from 1.3 to 1.6 µm . Such fibers are called dispersion-flattened fibers. The design of dispersion ...
