You are essentially observing an interference effect. This is equivalent to what you would see in a single slit experiment. The fringes are caused as the light rays that passes between your fingers are travelling slightly different distance to reach you eye. This causes their phases to be somewhat different. As a result the light rays partially cancel, ...

To add to Benito Caro's amusing, evocative and quite accurate analogy. The notion you cite that atoms can't be cut died about 100 years ago. There are two reasons this idea sometimes persists in modern culture and, although wrong, used the right way, it can be useful: The classical Greek name "atom" literally means "not cut" and thus refers either to ...

Think of an atom as a family with cats. The husband (neutron), wife (proton) and cat (electron) live in the house (atom). It's a bit more complicated because each house can have several husbands, wives and cats, so its more like a 1960s communal house, but anyway... The electron, like a cat, is somewhere in the house but you're never quite sure where. ...

$F_1 = F_2 = F_3$. This is essentially the superposition principle. We know that in an atom, for example, in a neutral oxygen atom there are 8 protons and 8 electrons, i.e., 8 positive charged particles and 8 negative charged particles. We know it's nucleus can only carry 8 electrons around it. Now my question is why can't it carry so many electrons, ...

Observables like quantised energy levels and quantised angular momentum of an atom are obtained by finding eigensolutions of the Schrödinger Equation (here for the Hydrogen atom). Separation into three parts allows to obtain the Colatitude and Azimuthal equations which allows to calculate the quantised angular momentum of the hydrogen atom, giving rise to ...

I agree with what John Rennie said, "A photon doesn't interact with a single electron, it interacts with the entire molecule." The 'probabilistic process' is a better way of stating 'Give it a shot, and see what happens.' The probability between relaxing and splitting, or whether the photon and the molecule reacts at all, sounds good to me. Please ...

When a molecule absorbs a photon it reaches to an excited state and there are various mechanisms in which the molecule can relax. Dissociation of the molecule is just one of the possibilities. It is not necessary to ionize (to separate the electron from) the molecule for dissociation to occur. What is necessary is to excite a bonding electron, that is, an ...

This isn't really how it works. A photon doesn't interact with a single electron, it interacts with the entire molecule. Suppose you take the example of ozone photolysis to $O_2$ and an oxygen atom. We can do a calculation for ozone and come up with a series of molecular orbitals, then put two electrons in each orbital. So far so good. But if you remove an ...

The simplest method is to follow Archemides and his principle: Archimedes' principle aids in the experimental determination of density by providing a convenient and accurate method for determining the volume of an irregularly shaped object, like a rock. We are in a fortunate position to have the densities of all elements with a click on the internet ...

One way to figure out what something is made of figure out its density by dividing the object's mass and volume;then look at a density chart!
