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...
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...
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...
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...
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...
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...
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 ...
Investigating Gas Laws Investigating Gay-Lussac's Law Aim of the Experiment? The aim of the experiment is to investigate the relationship between the pressure and the temperature of a gas at consta...
Mole Calculations The Mole The?mole?is one of the seven SI base units It is used to measure the?amount of substance? One mole is defined as follows: The amount of substance that contains as many el...
