Condensed Matter I | Physics Made Easy

Types of cohesive force. Transfer of electrons from one atom to another, leading to charged atoms with filled shells, e.g. Na. Unpaired valence electrons mix (hybridise) to give a lower energy state. Covalent bonding is very directional. Hybridisation, tetrahedral diamond structure. Outer atomic orbitals overlap several other atoms, so the electrons become mobile and delocalised (reducing KE). Metallic bonding is not directional, and is weaker than covalent bonding. Van der Waals forces:. Can contain mor...

Are born in warm molecular clouds; because of their size, they shape the environment around them through processes such as photoionisation, stellar winds and supernovae. It may also be the case that massive stars trigger or terminate the formation of less massive stars. Stellar collapse (low mass):. Cores collapse when their mass exceeds the Jeans mass. Over a timescale of 10. Yr The collapse stops when the material becomes optically thick and can no longer remain isothermal. This is a protostar. Are the...

Arises from closed atomic shells of electrons. When a B-field is applied, these electrons set up a screening current that opposes the applied field. Start by thinking of electrons in a circular orbit of radius. Force on an electron. Electrons in an atom. For a spherically symmetrical orbit (note that strictly we should be using the average values. Atoms per unit volume. Again note that strictly not all atoms will have the same. So really we need to consider. Similarly, in quantum mechanics. For the purpo...

Quantum wells and heterojunctions. If we put two undoped semiconductors together, the chemical potential must be continuous across the junction- this creates a heterojunction. Two such junctions can be put together to form a quantum well. In reality, this is a finite potential well, but we’ll treat it as an infinite one to make the maths easier. Electrons have energy levels. From the bottom of the conduction band. Holes have energy levels. From the top of the valence band. The laser transition is E.

Stars are self-gravitating bodies in dynamical equilibrium due to a balance of gravity and internal pressure forces. Equation of hydrostatic equilibrium:. Consider a small volume element at a distance r. From the centre- cross section. Equation of distribution of mass. Use this to estimate the central pressure. Consider a point at. The dynamical timescale is the time it would take the star to collapse completely if pressure forces were negligible. Latex 4 pi r 3dP r=-( frac{GM r}{r})4 pi r 2 rho rdr.

Protesting, we're reversing communism! To protest against the Police (Cong an) of Vietnam. Cong an are 100% belonging to North Vietnam which is Communist not a party but as a whole. This is a camera. Turn on the light to have your photo taken. Why not go outside? One beautiful afternoon walking with a friend and his small dog near the city. A while later, his dog did a poo. He pulled out some papers and picked up the poo and put it in the bin. Why did you pick up poo? When we reached a shop. Yes, it is!

Physics Made Easy…? Hello and welcome to Physics Made Easy, a site whose purpose is, unsurprisingly, to attempt to make physics, if not easy, at least less difficult. Unfortunately, making physics easy is no simple task in itself, and so the site is an ongoing project, continually adding and refining content in the hopes of reaching its stated goal.
