- For a particle in a state having the wavefunction =2asinxa in the range x=0toa, what is the probability that the particle exists in the following intervals? a x=0to0.02ab x=0.24ato0.26a c x=0.49ato0.51ad x=0.74ato0.76a e x=0.98ato1.00a Plot the probabilities versus x. What does your plot illustrate about the probability?arrow_forwardUnder what conditions would the operator described as multiplication by i the square root of 1 be considered a Hermitian operator?arrow_forwardShow that the normalization constants for the general form of the wavefunction =sin(nx/a) are the same and do not depend on the quantum number n.arrow_forward

If they are not, explain why not. aF(x)=x2+1,0x10 bF(x)=x+1,x+ cf(x)=tan(x),x d=ex2,x+arrow_forwardA particle on a ring has a wavefunction =12eim where equals 0 to 2 and m is a constant.

- 19) Describe requirements for the well-behaved wavefunction.arrow_forwardWrite the normalized form of the ground state wavefunction of the harmonic oscillator in terms of the variable y and the parameter α. (a) Write the integral you would need to evaluate to find the mean displacement <y>, and then use a symmetry argument to explain why this integral is equal to 0. (b) Calculate <y2> (the necessary integral will be found in the Resource section). (c) Repeat the process for the first excited state.arrow_forwardIn quantum mechanics, the measurements of two different physical properties are represented by the operators A and B. It is possible to know, exactly and simultaneously, the values of both measured quantities only if the (a) eigenfunctions of operator A form an orthonormal set and the eigenfunctions of operator B form an orthonormal set. (b) eigenfunctions for both operators A and B can be normalized. (c) eigenvalues for both operators A and B are real numbers. (d) operators A and B are both Hermitian. (e) operators A and B commute.arrow_forward
- (a) Consider the translational motion of a particle in a one-dimensional box of mass m, that is free to move between x = 0 and x = L: (i) State the boundary conditions that must be satisfied. (1) (ii) Draw rough sketches of three different boxes to illustrate the relationship between the energy separation and the increasing or changing length of the box. (3)arrow_forwardDescribe and justify the Born interpretation of the wavefunction.arrow_forwardUsing the wavefunctions for the particle in 1D box, show that the Hamiltonian is (a) a linear operator, and (b) Hermitian.arrow_forward
