WebA gold bullion bar is a brick-shaped gold bullion of .999 fine gold content. It can be minted or cast. A cast bar is done by pouring molten gold into a mold. Minted bars undergo a more precise process, which involves cutting thin layers of gold to create a perfect shape and run it through a machine press several times. WebRefraction, or bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves. So if the media (or its properties) are changed, the speed of the wave is changed.
