## What is de Broglie wavelength give its expression and explain it?

⇒λ=hp where λ denotes de Broglie wavelength of matter waves, h is planck’s constant (h=6.62607×10−34 Joule-sec) and p denotes the momentum of the matter wave. The above equation represents the required expression for de Broglie wavelength of matter waves.

## What does de Broglie equation describe?

The de Broglie equation is an equation used to describe the wave properties of matter, specifically, the wave nature of the electron:​ λ = h/mv, where λ is wavelength, h is Planck’s constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.

## What are de Broglie waves write the expression for it?

Note: If the charged particle is considered as the electron then the de Broglie wavelength for electron would be given as λ=h√2meV . This wavelength is of the same order as the spacing between the atomic planes in crystals.

## What is the significance of de Broglie’s wave equation?

Compton’s formula established that an electromagnetic wave can behave like a particle of light when interacting with matter. In 1924, Louis de Broglie proposed a new speculative hypothesis that electrons and other particles of matter can behave like waves.

## What is the unit of de Broglie wavelength?

meters
The unit of the de Broglie wavelength is in meters. Since it is very small and hence expressed in nanometres or Angstroms units.

## Which of the following is de Broglie wave equation?

Sample Problem: de Broglie Wave Equation Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron.

## What is the most important application of de Broglie concept?

Structure of Atom What is the most important application of de-Broglie concept? Its most important use is in the construction of electron microscope which is used in the measurement of objects of very small size.

## What is the deBroglie wavelength?

The wavelength (λ) that is associated with an object in relation to its momentum and mass is known as de Broglie wavelength. A particle’s de Broglie wavelength is usually inversely proportional to its force.

## What is the dimensional formula of a wavelength?

Wavelength = Distance between identical points in the adjacent cycles of a waveform Since, the dimensional formula of distance = [M 0 L 1 T 0 ] Therefore, the wavelength is dimensionally represented as [M0 L1 T0]. ⇒ Check Other Dimensional Formulas:

## Does a photon have a de Broglie wavelength?

Answer: The de Broglie wavelength of the photon can be found using the formula: The de Broglie wavelength of the photon is 442 nm. This wavelength is in the blue-violet part of the visible light spectrum.

## What is de Broglie?

De Broglie was the second son of a member of the French nobility. From the Broglie family, whose name is taken from a small town in Normandy , have come high-ranking soldiers, politicians, and diplomats since the 17th century.
