Fresnel diffraction occurs when the distance from the obstruction to the screen or the distance from the screen to the obstruction is comparable... View Article
Light is an electromagnetic wave that doesn’t need a medium to propagate. The strength of the wave, however, can get weaker with the distance,... View Article
There are two theories of light. In the seventeenth century, two contradicting theories of the nature of light were proposed: wave theory and the... View Article
The diffraction of waves is the phenomenon in which the waves spread out as they pass through an aperture or around objects. Diffraction occurs... View Article
The attractive forces in solid particles keep them together tightly enough so that the particles do not move past each other. In solids, the... View Article
In thermodynamics, an adiabatic process is one in which there is no exchange of heat between the system and its surroundings. One way to... View Article
