Physics Summary Sheet

Physics Glossary galvanic automobile circuit whiz simple, complete conducting circuit pathway Electronic thingmajig a work that consists of two-fold circuits and transducers Transducer blind that converts energy from one underframe to another Input transducer converts other forms of energy (sound, unclouded, heat) into electrical energy, e. g. microphone create transducer converts electrical energy into other forms of energy, e. g. peakers Processor Component found in electronic gadgets, receives signals from input transducer and responds by operating the output transducer Transistor device found in processors that can amplify electrical signals or enactment as a switch Diodes also found in processors, allows the electric current to flow in lone(prenominal) one direction Semi-conductor a material whose ability to conduct electricity is somewhere between a conductor and insulator LED a luminance emitting diode, which is a junction transistor which transforms ele ctric current into thermal and elation energy.Found in traffic lights, gondola lamps and indicator lights, and be sturdy, operate for a longer time and single-valued function less energy than standard lights.Integrated circuit a usually composite circuit with many components, and is packaged into a small unit called a chip Magnetic field is created when an electric charge moves it is a kingdom where a permanent experiences a charismatic force of attraction or repulsion Electro drawing card is created when a coil of cable is wrapped around a fleecy piece of iron when an electric current flows through the wire the magnetic field it creates causes the domains in the iron to line up, creating a inviolable magnet Domains the magnetic regions the iron atoms ar course themselves into that act like precise magnets with north and south poles Electricity The collection of physical effects colligate to the force and motion of electrically charged particles, typically electrons, through or across matter and space Electromagnetic Gadget A machine that consists of a coil wire wrapped around a soft piece of iron when electric current flows through the wire the magnetic field it creates causes the domains in the iron to line up, creating a strong magnet Light Electromagnetic radiation that can be perceived by the human eye, it is made up of electromagnetic waves Electromagnetic Spectrum A range of electromagnetic energy which includes light that we can see and light that we cannot see. An theoretical account of light we cannot see is radio waves Transparent Havingthepropertyoftransmittingraysoflightthroughits substance Translucent Permitting light to pass through notwithstanding diffusing it so that persons, objects, etc. , on the opposite side are not clearly visible Opaque Does not allow light to pass through Reflection Thechangeindirectionofawave,suchasalightorsoundwave,awayfromaboundarythewaveencounters Refraction When light travels from one medi um to another, it speeds up or slows down Our eyes contain two diametrical photoreceptors rods which watch over light and strobiles which detect glossary -our eye detects primary influence with only one type of cone -secondary comments created by multiple cones tinder simultaneously. Our eyes -contain two different photoreceptors rods which detect light and cones which detect colour -our eye detects primary colours with only one type of cone -secondary colours created by multiple cones firing simultaneously. Our eyes -contain two different photoreceptors rods which detect light and cones which detect colour -our eye detects primary colours with only one type of cone -secondary colours created by multiple cones firing simultaneously. Our eyes contain two different photoreceptors rods which detect light and cones which detect colour -our eye detects primary colours with only one type of cone -secondary colours created by multiple cones firing simultaneously. send off Our eyes -contain two different photoreceptors rods which detect light and cones which detect colour -our eye detects primary colours with only one type of cone -secondary colours created by multiple cones firing simultaneously Human bosom * We see images in our retinas because the fovea in the central of the retina controls the eyes sharpest plenty and is the location of most colour perception, which is how we see.
