# What is the de Broglie theory?

## What is the de Broglie theory?

De Broglie’s hypothesis of matter waves postulates that any particle of matter that has linear momentum is also a wave. The wavelength of a matter wave associated with a particle is inversely proportional to the magnitude of the particle’s linear momentum.

## When was the convention wave theory propounded?

The theory was historically developed in the 1920s by de Broglie, who, in 1927, was persuaded to abandon it in favour of the then-mainstream Copenhagen interpretation.

Is Bohmian mechanics deterministic?

This is the key to understanding how Bohmian mechanics, despite being deterministic, can account for all quantum predictions, including quantum randomness and uncertainty.

Why de Broglie wave principle is not reliable in daily life explain?

because de-broglie wavelength associated with the moving particle is very small as compared to its size so this phenomina is not observable in daily life…

### How does the electron behave according to de Broglie?

(1) In 1924, the French physicist, Louis de Broglie suggested that if light has electron, behaves both as a material particle and as a wave. (2) This presented a new wave mechanical theory of matter. According to this theory, small particles like electrons when in motion possess wave properties.

### Why is pilot wave theory not accepted?

Pilot-wave theory has no counterpart to explain particle behavior at near-light-speed, which is part of the reason it cannot explain particles existing in two places at once, or springing in and out of existence, as we seem to have observed.

Who is father of wave theory?

In his Traité de la Lumière (1690; “Treatise on Light”), the Dutch mathematician-astronomer Christiaan Huygens formulated the first detailed wave theory of light, in the context of which he was also able to derive the laws of reflection and refraction.

What is the velocity of de Broglie wave?

We can easily calculate a velocity for de Broglie waves. Beiser calls it “vp,” and later shows that vp is the phase velocity of the waves. A wave velocity is given by vp=fλ. De Broglie postulated that λ=h/mv for particles as well as waves.

#### Can Bohmian mechanics be made relativistic?

One common objection to Bohmian mechanics is that it is incompatible with, and cannot be made compatible with, relativity. Of course, the theory sketched above is a version of non-relativistic quantum mechanics, so one expects incompatibility with relativity.
