what quantity, combined with universal physical quantities, can be used to determine a particles de broglie wavelength? what quantity, combined with universal physical quantities, can be used to determine a particles de broglie wavelength? the particle's mass the particle's kinetic energy the particle's velocity the particle's momentum the particle's size

Sagot :

Louis de Broglie demonstrated that a particle's wavelength is equal to Planck's constant divided by its mass times its velocity.

the length of the wave that a moving particle produces. Given that h is the Planck constant, m is the particle's mass, and v is its velocity, the wavelength () is calculated as = h/mv. Any particle may exhibit wave-like characteristics. The length scale at which a particle's wave-like characteristics are significant is indicated by its de Broglie wavelength. Paul Dirac and others realized that the concept could be applied to electrons and everything else, in addition to photons, the quanta of light: According to quantum field theory, particles are excitations of quantum fields that occupy all of space.
