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.
How many types does heat transfer? There are three ways of heat tranfer. a) Conduction (transfer of heat among objects in direct contact) b) Convection (transfer of he
