Difference between EM wave & a Matter wave ?

In summary, the conversation is discussing the difference between an electromagnetic (EM) wave and a matter wave. The main difference is that a mechanical wave travels at a constant speed relative to its medium, while an EM wave travels at a constant speed relative to the observer. Additionally, EM waves are more fundamental and do not exist on a small scale like mechanical waves do.

Well, what do you mean by "a matter wave"?
Do you mean, for example, what is the difference between a light wave and a wave in a string?
 
  • #3
like we can take example of a tennis ball . Its mass is huge & by de broglie its wavelength is extremely small .

So what is the basic difference b/w EM wave & matter wave ?

A mechanical wave travels at a constant speed relative to its medium.

An electromagnetic wave travels at a constant speed relative to the observer.

That is the most significant difference in behavior as I see it.

Electromagnetic waves are also more fundamental. Mechanical waves are emergent phenomena when large numbers of atoms interact. Similar to heat or color, they do not exist on a sufficiently small scale.
 

Related to Difference between EM wave & a Matter wave ?

1. What is the main difference between an electromagnetic wave and a 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.

2. How do the properties of an electromagnetic wave differ from those of a matter wave?

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.

3. Can both electromagnetic waves and matter waves be described by the wave-particle duality?

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.

4. How do the energies of electromagnetic waves and matter waves compare?

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.

5. Why are electromagnetic waves and matter waves important in different fields of science?

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.
