Energy associated with matter waves of macroscopic objects

In summary, an object with a mass of 1kg moving at a speed of 1m/s has a de Broglie wavelength of 3.6x10-37, which theoretically corresponds to a huge amount of energy of 3x1011. However, this energy cannot be accessed in real life due to the extreme stability of the object's structure. Only under extreme conditions such as fusion or fission can a small amount of this energy be accessed, as seen in nuclear bombs or reactors. The only way to fully release all the energy from this object is by completely annihilating it with antimatter, a process currently only possible on an atomic scale. For perspective, 1kg of radium-226 can produce enough

Consider an object of mass 1kg moving with a speed of 1m/s. Theoretically , the de broglie wavelength associated with it is about 3.6x10-37. Now if we calculate the energy associated with this wave it comes out to be 3x1011. This is a huge amount of energy which could be very hazardous but it is not observed in real life.Why ?

An object of 1kg mass (the speed is negligible here) has a huge amount of energy stored within by the E=mC^2 famous formula.
However you cannot access this energy because this structure is very very stable.
Only in very extreme scenarios of fusion or fission you will be able to access small amount of this energy (like nuclear bombs or reactors)
The only way you can get all the energy out of this object is by annihilation it entirely with anti matter, operation which today can be done only in atomic scale.

P.S. just to have feeling of the energy stored, if you had 1kg of radium-226, by its alpha decay you can heat 1kg of water to boiling point for thousands of years and this is just a fraction of the energy.
 

What is the concept of energy associated with matter waves of macroscopic objects?

The concept of energy associated with matter waves of macroscopic objects refers to the energy that is carried by the particles that make up a macroscopic object, such as an atom or molecule. This energy is related to the wave-like behavior of these particles, which is described by the wave function in quantum mechanics.

How is this energy related to the mass of a macroscopic object?

According to Einstein's famous equation, E=mc^2, energy and mass are equivalent and can be converted into one another. In the case of matter waves of macroscopic objects, the energy of the particles is directly related to their mass, with larger and more massive objects having a higher energy associated with their matter waves.

What is the significance of the energy associated with matter waves of macroscopic objects in quantum mechanics?

The energy associated with matter waves is a fundamental concept in quantum mechanics as it helps to describe the behavior and properties of particles on a microscopic scale. It allows us to understand the wave-like behavior of particles and make predictions about their interactions and behavior in various systems.

How is the energy associated with matter waves of macroscopic objects measured?

The energy associated with matter waves is typically measured using spectroscopy techniques, which involve analyzing the electromagnetic radiation emitted or absorbed by the particles. This energy can also be measured indirectly through various experiments and calculations based on the principles of quantum mechanics.

Can the energy associated with matter waves of macroscopic objects be manipulated or controlled?

Yes, the energy associated with matter waves can be manipulated and controlled through various techniques such as changing the temperature or pressure of a system, applying external forces, or using electromagnetic fields. This allows us to control the behavior and properties of particles, which has important applications in fields such as technology and medicine.
