Diffraction grating experiment
The above graphic shows the basic Young s slits experiment. Considering the light as a wave, it is not difficult to see how interference occurs. Each slit acts like a new source of waves. The waves spread out (diffract) from each slit and begin to overlap. Like water waves, where a wave crest from one source coincides with a crest from the other source, they reinforce each other…

Hologram pattern
To understand how a hologram is made and viewed, we need to know about two important properties of light: interference and diffraction. To describe these properties, it is useful to think of light as a wave. All waves can be described as a series of crests (high points) and troughs (low points) where…

Holographic phones
UPDATE: The Amazon Fire Phone has been announced during a press event in Seattle and missing from its specifications is any kind of 3D support. Speculation in this case, it seems, was wide of the mark. Instead, it utilises a new Dynamic Perspective feature. The phone tracks your head to know which graphical…

Subatomic Universe theory
General relativity and quantum mechanics take different approaches at looking at how the universe works. Many physicists feel that there must be a method that unites the two. One contender for such a universal theory is superstring theory, or string theory, for short. Let s take a brief overview of this…

In ancient Egypt (so says Joan Grant, in Winged Pharaoh ), the priests taught by this formula: “I of my own knowledge tell you that this is the truth.” Not from hearsay, not from rote, but “of my own knowledge.” But who today can teach, from first-hand knowledge, the meaning of life, or the range of…

Determination of the wavelength by grid diffraction
The de Broglie hypothesis, formulated in 1924, predicts that particles should also behave as waves. De Broglie s formula was confirmed three years later for electrons (which have a rest-mass) with the observation of electron diffraction in two independent experiments. At the University of Aberdeen George…
