1 giorno fa · The concept that matter behaves like a wave was proposed by French physicist Louis de Broglie (/ d ə ˈ b r ɔɪ /) in 1924, and so matter waves are also known as de Broglie waves. The de Broglie wavelength is the wavelength , λ , associated with a particle with momentum p through the Planck constant , h :
2 giorni fa · To use algebra to find the de Broglie wavelength or momentum of a particle when either one of these quantities is given; The next real advance in understanding the atom came from an unlikely quarter - a student prince in Paris. Prince Louis de Broglie was a member of an illustrious family, prominent in politics and the military since the 1600's.
2 giorni fa · Indeterminism also appears in the Schrödinger wave equation at the heart of the Copenhagen view. Einstein had shown that light waves can act like swarms of particles, later called photons; in 1924, Louis de Broglie assumed the inverse, that tiny particles are also wave-like. In 1926, Schrödinger published his equation for these “matter ...
2 giorni fa · Given light of a certain wavelength, the momentum and energy of that light can be found using de Broglie's formula. This generalizes the naive formula \(p = m v\), which can't be applied to light since light has no mass and always moves at a constant velocity of \(c\) regardless of wavelength.

Among the similarities to the Rothschild portrait are her oval face, tightly parted hair, the position of her hands and fingers, and the coquettish expression; Jean-Auguste-Dominique Ingres, Public domain, via Wikimedia Commons .

3 giorni fa · In 1924, Louis de Broglie furthered the development of QM by making another bold claim: all particles possess wave-particle duality, where the momentum and energy of a particle are given by two relations: \[p= \hbar k = \frac{h}{\lambda}\] and \[E = \hbar \omega = \frac{{p}^{2}}{2m}\]
5 giorni fa · Electron microscopes use the magnetic properties of electrons, in conjunction with Louis de Broglie's hypothesis that electrons possess wave properties, to augment magnification to a whole new level.
