What is D broccoli wavelength?
de Broglie wavelength is an important concept while studying quantum mechanics. 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 main point of the de Broglie equation?
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 is meant by de Broglie wavelength?
What is the de Broglie wavelength of a heavier particle?
The heavier particle’s de Broglie wavelength, λ1 = h2m1K. The lighter particle’s de Broglie wavelength, λ2 = h2m2K. If m1>m2, then λ1<λ2. So, option (c) is correct.
What is the importance of de Broglie wavelength?
De Broglie proposed that as light exhibits both wave-like and particle-like properties, matter to exhibit wave-like and particle-like properties. This nature was described as dual behaviour of matter. On the basis of his observations, de Broglie derived a relationship between wavelength and momentum of matter.
How is de Broglie wavelength related to temperature?
If the thermal energy is not a source of kinetic energy of a moving particle, then the de Broglie wavelength of that particle is independent of the temperature. Hence the de Broglie wavelengths of emitted particles in photoelectric effect, radioactive radiation etc. have no relation with temperature.
How do you prove de Broglie equation?
Proof of de Broglie wavelength for electron
- De Broglie first used Einstein’s famous equation relating matter and energy, E=mc2,
- Using Planck’s theory which states every quantum of a wave has a discrete amount of energy given by Planck’s equation, E=hν,
- Since de Broglie believes particles and wave have the same traits, the two energies would be the same: mc2=hν.
What is the de Broglie wavelength associated with an electron moving with a speed of?
The de broglie wavelength associated with an electron is moving with a speed of 5.4×10^6m/s.
What is the de Broglie wavelength associated with an electron accelerated through a potential difference 100?
133nm.
What affects de Broglie wavelength?
The de Broglie wavelength of a particle is inversely proportional to its momentum.
What is the de Broglie principle?
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 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. A photon of wavelength 4 x 10-7 m strikes on metal surface, the work function of the metal being 2.13 eV.
What is the conclusion made by de Broglie?
De Broglie concluded that most particles are too heavy to observe their wave properties. When the mass of an object is very small, however, the wave properties can be detected experimentally. De Broglie predicted that the mass of an electron was small enough to exhibit the properties of both particles and waves.
How does de Broglie hypothesis explain the stability of these orbits?
How does de Broglie’s hypothesis explain the stability of these orbits? An atom has a number of stable orbits in which an electron can reside without the emission of radiant energy. Each orbit corresponds, to a certain energy level. Electrons revolve in a circular orbit.
What are stable orbits?
Gravity provides the force needed to maintain the stable orbit of both planets around a star and also of moons and artificial satellites around a planet. A stable orbit is one in which the satellite’s speed is just right – it will not move off into space or spiral into the Earth, but will travel around a fixed path.
What do you mean by Bahut stable orbit?
In 1913 Bohr proposed his quantized shell model of the atom (see Bohr atomic model) to explain how electrons can have stable orbits around the nucleus. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump. …
How does Bohr’s second postulate help explain stability of an atom?
According to de Broglie, a stationary orbit is that which contains an integral number of de Broglie waves associated with the revolving electron. Thus, angular momentum of electron revolving in nth orbit must be an integral multiple of h 2 π which is same as proposed by bohr’s second postulate defining stable orbits.
