Difference between EM wave & a Matter wave ?
mkbh_10 said:So what is the basic difference b/w EM wave & matter wave ?
The main difference between an electromagnetic wave and a matter wave is that electromagnetic waves are disturbances in the electromagnetic field, while matter waves are disturbances in the quantum mechanical probability amplitude. This means that electromagnetic waves are made up of oscillating electric and magnetic fields, while matter waves are associated with the movement of particles, such as electrons.
The properties of an electromagnetic wave, such as frequency, wavelength, and speed, are determined by the medium it travels through and are independent of the particle that produces it. On the other hand, the properties of a matter wave, such as momentum and wavelength, are determined by the particle that produces it and are independent of the medium it travels through.
Yes, both electromagnetic waves and matter waves can be described by the wave-particle duality, which states that all particles exhibit both wave-like and particle-like properties. This means that both types of waves can exhibit diffraction, interference, and polarization, similar to particles.
The energy of an electromagnetic wave is directly proportional to its frequency, while the energy of a matter wave is directly proportional to its momentum. This means that for a given frequency, an electromagnetic wave will have a higher energy than a matter wave with the same momentum.
Electromagnetic waves are important in fields such as physics and engineering, as they are used in various technologies such as communication, imaging, and energy production. Matter waves, on the other hand, are important in fields such as quantum mechanics and particle physics, as they help us understand the behavior of particles at the subatomic level.
