Electronify vs Huygens3D

Quantum mechanics is a fascinating field that helps us understand the behavior of matter and energy on a microscopic level. One of the most important concepts in quantum mechanics is the idea of atomic orbitals. An atomic orbital is a mathematical function that describes the probability of finding an electron in a particular location around an atom's nucleus. Each electron in an atom can be described by a unique set of four quantum numbers, which determine its energy level, angular momentum, magnetic moment, and spin. The shape of each atomic orbital can be accurately depicted using a formula called spherical harmonics, which creates a visual representation of the electron's probable location around the nucleus. These representations are often shown as a series of dots, each representing a probable location of where an electron might be. The VSEPR (Valence Shell Electron Pair Repulsion) theory, on the other hand, is a model used to predict the geometry of molecules based on the arrangement of electrons in their valence shells. According to this theory, the electrons in a molecule's valence shell repel each other, and their repulsion determines the molecule's shape. The VSEPR model predicts a range of molecular shapes, including linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. These shapes can be used to predict a molecule's physical and chemical properties, such as polarity and reactivity.

Huygens3D brings the exploration of fundamental wave phenomena to iPad and iPhone, making it a full alternative to the classic ripple tank in physics lessons. Interference, diffraction, reflection and refraction are simulated just like in a real water tank. Thanks to the intuitive controls, every experiment is set up in seconds, so all students can experiment on their own. Features: • various wave sources (point, line, points on a line, circle), as a continuous wave or a wave packet • various obstacles, slits, prisms and lenses • rain field for random waves • pause and step-by-step mode • phase probes with an oscilloscope view showing the phase difference • tape measure for measuring in length units and in multiples of the wavelength • screen showing interference and diffraction patterns • share experiment setups via AirDrop, Messages or Mail
