Longitudinal Waves and Guitar Strings
According to the diagram this pressure wave consists of rarefactions and compressions. The compressions are regions of high pressure, whereas the air molecules are compressed within a small region of space. The rarefactions are regions of low pressure, while the air molecules are spread apart. This alternating pattern of compressions and rarefactions is called as a sound wave.
A crown glass prism has refractive indices 1.575 and 1.585 for blue and red colours. Determine its dispersive power. What are the basic conditions for a pair of thin prisms to p
Anti ferromagnetic materials such as chromium have a small but positive susceptibility. They cannot possess any magnetization is the absence of an applied field, in contrast to fer
what is Friction When we think about friction, there is one more place for energy to go - heat. When you push a book across a table, does the energy of the book change? Not if in
