Top 6: Waves/In Tech
Topic 6: Waves and Information Technologies
| Term | Definition |
|---|---|
| electric circuit | a complete, unbroken path through which electrical charges can flow |
| voltage | the difference in electrical potential energy per charge between two places in a circuit |
| resistance | the measurement of how difficult is it for charges to flow through an object |
| Ohm's law | the law that states that resistance in a circuit is equal to voltage divided by current |
| series circuit | an electric circuit in which all parts are connected one after another along one path |
| parallel circuit | an electric circuit in which different parts of the circuit are on separate branches |
| wave | a disturbance that transfers energy from place to place; the movement of energy through a body of water |
| mechanical wave | a wave that requires a medium through which to travel |
| transverse wave | a wave that moves the medium at right angles to the direction in which the wave travels |
| longitudinal wave | a wave that moves the medium in a direction parallel to the direction in which the wave travels |
| amplitude | the height of a transverse wave from the center to a crest or trough; the maximum distance the particles of a medium move away from their rest positions as a longitudinal wave passes through the medium |
| wavelength | the distance between two corresponding parts of a wave, such as the distance between two crests |
| frequency | the number of complete waves that pass a given point in a certain amount of time |
| electronic signal | information that is sent as a pattern in a controlled flow of current through a circuit |
| electromagnetic signal | information that is sent as a pattern of electromagnetic waves, such as visible light, microwaves, and radio waves |
| digital signal | a signal that allows for a record of numerical values of an action set of continuous time intervals |
| analog signal | a signal that allows for a continuous record of some kind of action |
| pixel | a small, uniform shape that is combined with other pixels to make a larger image |
| information technology | computer and telecommunication hardware and software that store, transmit, receive, and manipulate information |
| software | programs that encode, decode, and interpret information |
| noise | random signals from the environment that can alter the output of a signal |
| bandwidth | the amount of information that can be transmitted in bits per second |
| crest | highest point on a transverse wave |
| trough | lowest point on a transverse wave |
