How is De Broglie wavelength related to mass?
Louis de Broglie showed that the wavelength of a particle is equal to Planck’s constant divided by the mass times the velocity of the particle.
What is the De Broglie wavelength of a proton?
0. 9×10−19nm.
What is the ratio of De Broglie wavelength of proton and electron?
The ratio of De Broglie wavelength of electron and proton is 0.0233.
What is the De Broglie wavelength of the electron?
Applications of de Broglie Waves 10 eV electrons (which is the typical energy of an electron in an electron microscope): de Broglie wavelength = 3.9 x 10-10 m. This is comparable to the spacing between atoms.
How wavelength of electron wave is related with its mass?
The wave length of an electron wave is inversely proportional to mass and velocity.
When an electron and proton have same de Broglie wavelength they will have equal kinetic energy?
A proton and an electron have same de-Broglie wavelength which of them moves fast and which possesses more K.E. Justify your answer. If is constant, then from equation (i), p = constant. It means the velocity of electron is greater than that of proton. Kinetic energy of electron is greater than that of proton.
What is the wavelength of a proton?
The de Broglie wavelength of a proton in a particle accelerator is 1.30×10−14 1.30 × 10 − 14 m.
