# splitting Definition and Topics - 7 Discussions

Wood splitting (riving, cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing, the wood is split along the grain using tools such as a hammer and wedges, splitting maul, cleaving axe, side knife, or froe.

1. ### I 3p->2s: Why spectral line split into three lines in m. field

Hello, suppose we have an excited hydrogen atom in 3p state which makes a transition to 2s state. Then the atom loses some energy by emitting a photon which can be detected (or seen). I have no problems with that situation. If there is an external magnetic field, the energy levels of the...

### Springs and Splitting Mass Concept Confusion

Am I thinking about this problem correctly? "A block is attached to a horizontal spring and oscillates back and forth on a frictionless horizontal surface at a frequency of 3 Hz. The amplitude of the motion is 5.08 x 10-2 m. At the point where the block has its maximum speed, it suddenly splits...
3. ### NMR Diastereotopic Proton Splitting

This is one of those questions that probably has a very simple answer, but I can't find it anywhere, and as much as I think about it, the more confused I get. Can diastererotopic protons have different number of split peaks in their overall signal like on a CH2R group, for example, one proton...
4. ### Crystal phase transition, Diffraction peak splitting problem

Homework Statement [/B] Hi there! This is a question from a practice problem sheet I got from the lecturer of my Condensed Matter 1 course. Below are the normal vectors to the {111} and {112} lattice planes: Homework Equations [/B] Bragg Condition: \begin{equation} n \lambda = d \sin...
5. ### Simple expression for Coloumb energy

How did they arrive at this expression? I understand the ##Q^2## term in the nominator and the ##r = r_0 (A)^{\frac{1}{3}}## term in the denominator. Where did the ##\frac{\alpha}{2}## term come from? Putting in Z=40, A=100 gives ##3.3 \times 10^{14} J##, not ##65 MeV##. The energy term...
6. ### NMR: Why do "identical" protons not experience splitting?

Hey, I've been trying to figure out why a protons in identical environments will not undergo spin-spin splitting with one another. From what I understand splitting of a signal for a proton is due to the nucleus of another nearby either opposing the external magnetic field or acting in the same...
7. ### Hyperfine Interaction Splitting

Homework Statement (a)Find splitting between F=0 and F=1 in hydrogen (b) Find the constant ##A## and nuclear magnetic moment Homework Equations The Attempt at a Solution Hyperfine splitting is given by: H_{hf} = \frac{A}{2} \left[ F(F+1) - I(I+1) - J(J+1) \right] The intervals are...
