What is the De Broglie wavelength of an electron that strikes the back of the face of a TV screen at 19 the speed of light?
The De Broglie wavelength of an electron is given by the equation λ = h / p, where λ is the wavelength, h is the Planck constant, and p is the momentum of the electron. The momentum of an electron is p = mv, where m is the mass of the electron and v is its velocity. Since the electron is moving at 19 times the speed of light, its velocity is v = 19c, where c is the speed of light. Plug in these values to calculate the De Broglie wavelength.
When did Louis de broglie discover electron waves?
Louis de Broglie proposed the theory of electron waves in 1924 as part of his doctoral thesis, which suggested that electrons have both particle-like and wave-like properties. This marked a significant contribution to the development of quantum mechanics, laying the foundation for wave-particle duality and the concept of matter waves.
Does the de broglie wavelength of a photon become longer or shorter as its velocity increases?
The de Broglie wavelength of a photon remains constant as its velocity increases because a photon always travels at the speed of light in a vacuum. The wavelength of light is determined by its frequency according to the equation λ = c / f.
What did the equation e equals hv help Louis De Broglie determine?
The equation E = hv helped Louis de Broglie determine that particles like electrons could exhibit both wave-like and particle-like behaviors. This led to the development of wave-particle duality in quantum mechanics.
Determine wavelength for electron having velocity 15.0 the speed of light?
To determine the wavelength of an electron with a velocity of 15.0 times the speed of light, you can use the de Broglie wavelength formula: λ = h / (m*v), where λ is the wavelength, h is the Planck constant, m is the mass of the electron, and v is the velocity. Plugging in the values (mass of electron, velocity), you can calculate the wavelength of the electron.
If proton and an electron have the same speed which has the longer de Broglie wavelength?
The de Broglie wavelength is inversely proportional to the mass of the particle. Since a proton is much more massive than an electron, it will have a shorter de Broglie wavelength at the same speed.
What is de broglie's wavelength of electron in meters travelling at half a speed of light?
4.2*10-11

Who proposed the dualistic nature of light and extended this idea to electrons?
In 1924 de Broglie proposed that a material particle such as an electron might have a dual nature.
An electron starting from rest accelerates through a potential difference of 388 V What is the final de Broglie wavelength of the electron assuming that its final speed is much less than the spee?
To find the final de Broglie wavelength, you can use the equation λ = h/p, where λ is the wavelength, h is Planck's constant, and p is the momentum of the electron. The momentum can be calculated as p = √(2mE), where m is the mass of the electron and E is the kinetic energy acquired from the potential difference. Find the final speed of the electron using the equation v = √(2eV/m), where e is the elementary charge. Finally, use the speed to calculate the final momentum and plug it into the de Broglie wavelength formula.
How de broglie's hypothesis help to explain the stability of the atom?
de broglie explain stability of atom by explaining that like in standing waves energy does not transfer and as we say that every shell has definite energy so the electron exist in atom in form of waves as whole number of standing waves
When did Jean de Broglie die?
Jean de Broglie died in 1976.
How did de broglie test his theory?
de Broglie waves for electrons have wavelengths similar to that of x-rays, which diffract when sent through certain crystals according to the Laue phenomenon. These wavelengths where fist confirmed by diffraction by Davisson and Germer.
What is Jean de Broglie's birthday?
Jean de Broglie was born on June 21, 1921.
When was Jean de Broglie born?
Jean de Broglie was born on June 21, 1921.
