Dualismo onda particella Flashcards
What is the period of a wave described by the equation W(x,t) = Woe^(i2πkx-e^(i2πku)t)?
The wave has a spatial periodicity defined by a wavelength λ = 1/k and a temporal periodicity with period T = 1/ku.
What is the equation for kinetic energy?
T = p^2/2m = E - V
What is the equation for the normalization of Ψ?
∫|Ψ(x)|^2dx = 1
What is the implication of the probabilistic interpretation of Ψ compared to the classical approach?
The probabilistic interpretation of Ψ implies a radical change in the perspectives of physics, which loses its deterministic character: in the microscopic world, we can no longer predict with certainty certain future events, given certain present events, but we are only allowed to predict with what probability these events will occur.
What is the relationship between momentum, energy, and wavelength?
p = h/λ = hν/u = E/u
What is the equation that describes a generic wave phenomenon in space and time?
W(x,t) = Woe^(i2πkx-e^(i2πku)t)
What is the equation of Schrödinger’s wave equation?
(-h^2/8π^2m)∂^2Ψ(x)/∂x^2 + VΨ(x) = EΨ(x)
What is the equation of the wave equation?
∂^2W(x,t)/∂x^2 = (1/u^2)∂^2W(x,t)/∂t^2
What is the interpretation of the probabilistic interpretation of Ψ?
According to the Copenhagen interpretation, we have a frequentist meaning of the probabilistic interpretation of Ψ. This means that the total probability must be equal to one, which requires normalization.
What is the dualism of wave-particle?
The behavior of light (electromagnetic radiation) presents a strange behavior: in interference and diffraction experiments it behaves undoubtedly as a wave, while in other experiments such as the photoelectric effect it behaves as a set of particles (photons). These two aspects are inseparable and both must be accepted.
