waves that do not require matter to transfer energy are

Under certain experimental conditions, a beam of particles (for example, electrons ) can exhibit wavelike properties. Such matter waves are governed by the laws of quantum physics. The wavelength is inversely proportional to the momentum of the particles. These are also known a..

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 radiatio..

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,..

The important differences between electromagnetic waves and matter waves are given below: Electromagnetic waves Matter waves Electromagnetic are associated with electric and magnetic fields perpendicular to each other and to ..

Introduction - 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..

Electric bell suspended inside an airtight glass bell jar An electric bell is suspended inside an airtight glass bell jar connected with a vacuum pump. As the electric bell circuit is completed, the sound is heard. Now if the air is slowly removed from the bell jar by using a vacuum pump, the i..

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. ..

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 preceding one, though not at the same time. There is no onward moti..
