De Broglie wave Application
Homework Answers
The de Broglie equation gives the relationship between a moving particle's wavelength and its momentum. If ? is the de Broglie wavelength and p is its momentum and h is the Planck constant, then
According to de Broglie hypothesis, matter behaves like the particle as well as waves. All matter exhibits properties of both particles and waves
Interference and diffraction prove the wave nature of light While the photoelectric effect proves the particle nature of light and this behaviour is known as the Wave-Particle Duality.
De Broglie equation says that every moving particle whether microscopic or macroscopic is associated with a wavelength.

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...

Please explain which one is correct and why
In 1923, de Broglie argued that since light can display wave and particle properties, then matter can also be a particle and a wave too. Using dimensional analysis, then according to de Broglie the wavelength of an electron of mass m_e moving at velocity nu is given by A) lambda = m_e nu/h B) lambda = Squareroot_e nu/h C) lambda = h/m_e nu D) lambda = Squareroot h/m_e nu E) lambda =...

Part B
The hypothesis that was put forward by Louis de Broglie in 1924 was astonishing for a number of reasons. An obvious reason is that associating a wavelike nature with particles is far from intuitive, but another astonishing aspect was how well the hypothesis fit in with certain parts of existing physics. In this problem, we explore the correspondence between the de Broglie picture of the wave nature of electrons and the Bohr model of the hydrogen atom. What...

Which statement about the wave function for a single electron is NOT correct? 1- Louis de Broglie postulated that the wavelength of an electron is given in terms of Planck's constant and its momentum, λ = h / p. 2- A French graduate student named Louis de Broglie first had the idea that an electron should be described as a wave. 3-The amplitude of a wave function at a particular point in space equals the probability density of finding the...
