HI, i have a set of data that i want to plot with matlab, using an equation. i have all x data points and want to generate y values for each x data point. function y =marko(x) y= (4.11/1.98)*{(1/4*((1-x/L).^2))-(1/4)-(x/L)}; x=(218+data points) from the command window i have...

Hi, i have been working on this problem for a while. i just need some guidance. the question is: design a ztube scanner suitable for displacing ±1 micron displacement at 200V. i am using this equation: ΔL=([d]_{}[/31]×V×L)/t ΔL=(d31 ×L×V)/t ΔL=change in length = 1micron...

lets say? Exam worth: 70% exam percentage scored: 40% what is the exam mark?

i have attached a file with integration of wavefunction. so i integrated the wavefunction, I am just not sure of the steps. for example> if i want to work out the expectation value of energy. what exact steps do i follow.. im just confused with the terminology of what I am asked.

is k the bond strength? from equation λ=2pic\sqrt{u/k} do we then solve for K, to give the bond strength? thanks a mill :)

E=h(n+1/2)w

√Homework Statement Carbon monoxide molecule, which has a reduced mass of 6.85 amu, absorbs infrared radiation wavelength of 4.6um. if the absorption is due to vibrational transitions, calculate the strength of the bond in molecule Homework Equations u=(m1*m2)/(m1+m2) The Attempt at...

can you explain that again please

the lowest value for n is 1, this gives the smallest orbital radius 0.0529nm(bohr radius) L=r*p=mvr m=9.1e-31, v=20m/s r=0.5nm mvr=nhbar L=n h/2pi=nhbar

do i have to presume that n=1 before i continue the calculation, because there is no mention of principal quantum number in the question?

is it possible to find the value of the quantum number "l" (azimuthal quantum number)?

is it L=\sqrt{l(l+1)hbar}

Homework Statement a classical electron moves in a circle of radius 0.5mm with velocity 20ms-1 what is the value of the quantum number L which gives a quantised angular momentum close to the angular momentum of this classical electron? Homework Equations L=r * p The Attempt at a...

ive done some working out..

does this explain the origin of position-momentum uncertainty, using gaussian wavepacket.
