was an alloy of aluminium and manganese. Under an electron microscope, the alloy produced a diffraction pattern in which concentric circles, each made of ten dots, had five-fold rotational ...

Captured here is a laser diffraction pattern, visible as a series of concentric circles with a bright central area. This pattern is a result of light waves spreading out and overlapping after passing ...

The pattern is made of concentric circles, with a bright 'Airy disk ... Graney calculated the intensity of the diffraction pattern for stars of different brightnesses. He then worked out ...

cells subject to physical stress from crowding by neighbors can find some relief by dramatically slowing their own growth—and ...
