The wavelength of matter at rest is typically referred to as the de Broglie wavelength, named after physicist Louis de Broglie. It is a measure of the wavelength associated with a particle's wave-like behavior.
The de Broglie wavelength can be calculated using the formula λ = h/mv, where λ is the wavelength, h is Planck's constant, m is the mass of the particle, and v is the velocity of the particle.
The de Broglie wavelength is significant because it shows that even particles with mass, such as electrons and protons, exhibit wave-like properties. This helped to bridge the gap between classical mechanics and quantum mechanics.
Yes, the de Broglie wavelength of a particle can change depending on its velocity. As the velocity of a particle increases, its wavelength decreases.
The de Broglie wavelength is related to Heisenberg's uncertainty principle, which states that it is impossible to know both the precise position and momentum of a particle at the same time. The de Broglie wavelength represents the uncertainty in the momentum of a particle at a given moment.
