IB DP Physics: SL复习笔记4.2.4 Sound Waves
Sound Waves Sound waves are longitudinal waves and, as such, require a medium in which to propagate Sound waves are generated by oscillating sources, which produce a change in density of the surrou...
IB DP Physics: SL复习笔记4.2.3 Electromagnetic Waves
Electromagnetic Waves An electromagnetic wave is generated by the combined oscillation of an electric and a magnetic field These fields oscillate perpendicular to each other and to the direction of...
IB DP Physics: SL复习笔记4.2.2 Transverse & Longitudinal Waves
Transverse & Longitudinal Waves In mechanical waves, particles oscillate about fixed points There are two types of wave: transverse and longitudinal The type of wave can be determined by the di...
IB DP Physics: SL复习笔记4.2.1 Properties of Waves
Properties of Waves Travelling waves are defined as follows: Oscillations that transfer energy from one place to another without transferring matter Energy is transferred by the waves, but matter i...
IB DP Physics: SL复习笔记4.1.4 Energy in SHM
Energy in SHM The total energy of an object oscillating with SHM is the sum of its potential energy (gravitational or elastic) and kinetic energy E = EP + EK Where: E = total energy in joules (J) E...
IB DP Physics: SL复习笔记4.1.3 SHM Graphs
SHM Graphs Displacement & Velocity The displacement-time graph for an object moving with SHM is a sinusoidal curve if: The object starts to oscillate from the equilibrium position. The equilibr...
IB DP Physics: SL复习笔记4.1.2 Simple Harmonic Oscillations
Simple Harmonic Oscillations Simple harmonic motion (SHM) is defined as follows: The motion of an object whose acceleration is directly proportional but opposite in direction to the object's displa...
IB DP Physics: SL复习笔记4.1.1 Properties of Oscillations
Describing Oscillations An oscillation is defined as follows: The repetitive variation with time t of the displacement x of an object about the equilibrium position (x = 0) A pendulum oscillates be...
