waves transfer energy without transferring matter

Energy Transfer and Energy Transformation - Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The rad..

Modes of Transference of Energy - Chemical reactions are accompanied by the energy changes. The exchange of energy between the system and surroundings can occur in several ways. Two of the important modes of transference of energy are heat..

We know that there is a transfer of energy, as heat, between a system and its environment. Here we discuss how this transfer takes place. There are three mechanisms of heat transfer. They are conduction, convection and radiati..

Wave Nature of Particles - The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles,..

Very often, energy is generated at one place but consumed elsewhere. The transportation of energy from its source to the receiving end can be done in two ways: By actually moving the matter carrying kinetic energy and delivering it to the other en..

Comparison between Progressive Waves and Stationary Waves - Progressive waves Stationary waves The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the ..

>All along when we were discussing about transverse and longitudinal waves the disturbances, which cause them were continuous. But the disturbances always need not be continuous i.e., it might last only for a short duration. For example: Take a slinky and fix one of its ends to a hook as ..

But mn = mass per unit volume = density ( r ) The transfer of energy per unit time per unit area, perpendicular to the direction of motion of the wave, is called the intensity (I) of the wave. In unit time, the wave will have traveled a distance v. ..
