Use the quantized energy expression of a “particle in a box” for the following problem. Imagine a “linear” conjugated molecule that has a length of 576 pm. To the nearest ones, what is the wavelength of EM radiation (in nm) that will excite a pi electron from n = 4 to the next higher quantum level (i.e., n = 4 +1)? Some helpful information: En = h2n2/(8mea2), where En is the energy of the particle (electron) at the nth quantum...
Problem 3. Calculate a) the average momentum and b) the average position of a particle, of mass m in a one-dimensional box of length L by evaluating specific integrals.
Could you please answer this question by clear handwriting
UESTION 2 A particle of mass m moves in a one- dimensional box of length Lwith boundaries at x-0 and x - L. Thus, V(x) - 0 for 0 x L and V(x) elsewhere. The normalized eigenfunctions of the Hamiltonian for the system are given by 1/2 -| sin 1-_- , with -, where the quantum number 2ml2 n can take on the values n -1, 2, 3, (i). Assuming that...

for a particle in a one dimensional box of length L if the particle is on the n=4 state what is the probability of finding the particle within a) 0<x<5L/6 b) L/4<x<L/2 c) 5L/6<x<L
2. (a) When a particle of mass 1.0 x 10-26 g in a one-dimensional box goes from the n=3 level to n=1 level, it emits a radiation with frequency 5.0 x 1014 Hz. Calculate the length of the box. (b) Suppose that an electron freely moves around inside of a three-dimensional rectangular box with dimensions of 0.4 nm (width), 0.4 nm (length), and 0.5 nm (height). Calculate the frequency of the radiation that the electron would absorb during its transition...

What is the probability of finding a particle between x = 0 and x = 0.25 nm in a box of length 1.0 nm in (a) its lowest energy state (n = 1) and (b) when n = 100. Relate your answer to the correspondence principle. This is an illustration of the correspondence principle, which states that classical mechanics emerges from quantum mechanics as high quantum numbers are reached. What does this all mean? • Only certain (discrete) energies are...
