Diffraction 10 Dec 2012 | 04:00 am
When a wave arrives at an opening of very small dimension (on the order of magnitude of the wavelength), it is diffracted, that is to say, the wave front is rounded and widens. Behind the slit, areas...
Interference fringes 7 Dec 2012 | 04:00 am
When two light waves of the same frequency, the same amplitude, and phase arrive at a point on a screen, they are superimposed, giving rise to an "interference pattern." Maximum illumination zones, an...
Energy Level Diagram 11 Jun 2012 | 03:00 am
Each atom is characterized by its electron configuration. Quantum theory, developed by Planck and Bohr in the early twentieth century, states that the energy of an atom can only have certain specific ...
