Nuclear Scattering Electrons accelerated to close to the speed of light have wave-like properties such as the ability to diffract and have a ?de Broglie wavelength?equal to: Where: h?=?Planck's con...
Rutherford Scattering & Nuclear Radius In the Rutherford scattering experiment, alpha particles are fired at a thin gold foil Initially, before interacting with the foil, the particles have kin...
Tunnelling Single potential wells?lead to quantised energy levels and their associated?wavefunctions The wavefunction extends throughout space However, for?infinitely deep square wells?the wavefunc...
為了向大學(xué)招生官展示你的學(xué)術(shù)能力，在高中期間選修AP課程很重要，而AP課程門類繁多，如果沒有明確的目標(biāo)專業(yè)，選課會令人感到非常頭禿。在很多成功的申請案例中，有手握十幾門AP 5分的學(xué)生，也有只考一兩門AP的...
The Uncertainty Principle The quantisation of energy levels and their associated wave functions leads to some surprising outcomes One of these outcomes is known as the?uncertainty principle The unc...
The Wave Function Bohr?showed that the angular momentum of an electron orbiting a hydrogen atom was?quantised He also showed that the allowed electron energies were also quantised Unfortunately, th...
Quantization of Angular Momentum Angular momentum is a property of any spinning or rotating body, very similar to?linear momentum In linear motion, momentum is the product of mass and velocity In r...
Pair Production & Annihilation Annihilation When a particle meets its antiparticle pair, the two will?annihilate Annihilation is: When a particle meets its equivalent anti–particle they both ar...
Matter Waves De Broglie proposed that electrons travel through space as a wave This would explain why they can exhibit behaviour such as diffraction He therefore suggested that electrons must also ...
