The phenomenon of forming an interference pattern by using light that passed through a double slit is a basic item learnt in a high school physics course. It is a good example that light possesses a ...

Electrons travelling through two slits and a single slit. (Courtesy: Herman Batelaan/New Journal of Physics) Physicists in the US and Canada say that they have done the best job yet of realizing ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...
