Apr 14, 2005 · This gives us the conversion factor of 1 cm^-1 = 1/wavelength eV. Plugging in the value for wavelength (in meters), we get 1 cm^-1 = 1/(wavelength in cm * 0.01) eV. Simplifying this, we get 1 cm^-1 = 0.00012398 eV. Therefore, to convert from cm^-1 to eV, we simply need to multiply the value in cm^-1 by 0.00012398.

Apr 20, 2014 · In a velocity selector apparatus, i had an electric potential set across two points, and a proton at rest at one end. The potential was 350 V. My instructor used : qV = 1/2 mv^2 to find the velocity at the end of the apparatus. Where did the left hand side of the eqn come from??

Aug 27, 2011 · B Is time travel... travelling from one 3 dimensional space time to another 3 dimensional space time?

Jul 7, 2021 · An infinitely deep square well has width L = 2.5 nm. The potential energy is V = 0 eV inside the well (i.e., for 0 ≤ x ≤ L). Seven electrons are trapped in the well. 1)What is the ground state (lowest) energy of this seven electron system? 2)What is …

Mar 6, 2025 · I know from a table in my textbook that the cross-section for the ionized cloud is ##6.3*10^{-18} cm^2##, but I don't know L, the distance a particle travels, or n, the number of particles in the cloud. Maybe I can assume L is very far given the vantage point is on the surface of Earth, but then I don't know what n would be.

Apr 28, 2011 · V is used for electromotive force, eV is energy and actually means the energy gained by an electron moving through a 1 V potential difference. So you can't really convert between the two. Perhaps it would be more useful to picture V …

Jan 9, 2011 · It can be shown that the allowed energies of a particle of mass m in a two dimensional square box of side L are E =h 2 (n 2 +m 2)/8mL 2 The energy depends on two quantum numbers, n and m, both of which must have an integer value 1, 2, 3... What is the minumum energy for a particle in a two dimensional quare box of side L?

Dec 5, 2009 · Okay, I just need to grasp what the equation C = Vλ means . Correct me if I am wrong. c = speed of light v = speed of frequency λ = wavelength So if I wanted to find the speed of the frequency of a photon with a wavelength of 450nm So I …

Oct 20, 2005 · In an intrinsic semiconductor, Ef is the fermi energy and sits right in the middle of the band gap. Ec and Ev are the energy of the bottom of the conduction band and the energy of the top of the valence band, respectively. This means that Ec - Ev = Egap. It also means that since Ef is right in the middle of the gap, Ec - Ef = Egap/2

Mar 12, 2013 · My mechanics syllabus suggests that we can model acceleration as ##v(dv/dx)## but what exactly does this mean? Can you give me (or link me to) some explanations and/or sample problems with worked solutions? In my experience so far we should always be using ##dv/dt## for ##a##.
