- What is the Born approximation and how does it apply to the scattering of particles in quantum mechanics?Describe the concept of wave-particle duality and provide examples of experiments that support this principle.Already asked but they given wrong answer. Please provide correct one What is the energy of a photon that could cause an electron to transition from the ground state to the n = 6 energy level in an infinite well of width L = 2nm ?
- Explain the the history of quantum entanglement and the physicist, who worked on the theory.List two requirements of a well-defined wave function, based on the postulates of quantum mechanics.Explain in your post how the x-ray is produced. As you describe the process, be sure to identify what is the source of free electrons, and define the concepts of electron acceleration, focusing of electrons, electron deceleration, target interactions, and Bremsstrahlung radiation in terms of their relation to the process. Also, describe the photon interaction with matter in relation to the Compton effect, photoelectric absorption, coherent (classical) scatter, and attenuation by various tissues. Explain the characteristic of the x-ray beam with respect to the frequency and wavelength.
- If the formalism of quantum mechanics is 'more exact' than that of classical mechanics, why don't we use quantum mechanics to describe the motion of a leaping frog? Explain.Can a quantum particle 'escape' from an infinite potential well like that in a box? Why? Why not?Suppose a quantum particle is in its ground state in a box that has infinitely high walls (as shown). Now suppose the left-hand wall is suddenly lowered to a finite height and width. (a) Qualitatively sketch the wave function for the particle a short time later. (b) If the box has a length L, what is the wavelength of the wave that penetrates the lefthand wall?
- I need help with this question. Can you show me step by step? Please and thank you! For a particle in a one-dimensional box in its ground state calculate the probability that theparticle is in the middle third of a box?What is a quantum state? How are quantum states represented in the formalism of quantum mechanics?Does the uncertainty account for all random errors? How ? Explain your answer and give detail.
