WAVES
Energy: Light , Sound, Heat Transfer,
| Question | Answer |
|---|---|
| Conduction | The transfer of thermal energy through touching |
| convection | the transfer of thermal energy through liquids and gases |
| radiation | the transfer of heat energy through waves |
| transfer | to move from one location to the next |
| vibration | a periodic motion of the particles of an elastic body or medium in alternately opposite directions from the position of equilibrium when that equilibrium has been disturbed |
| medium | a substance regarded as the means of transmission |
| rarefaction | a state or region of minimum pressure in a medium traversed by compressional waves (such as sound waves) |
| infrared | situated outside the visible spectrum at its red end —used of radiation having a wavelength between about 700 nanometers and 1 millimeter |
| frequency | the number of times that a periodic function repeats the same sequence of values during a unit variation of the independent variable |
| longitudinal wave | particles of the medium vibrate in the direction of the line of advance of the wave |
| compression | a longitudinal wave (such as a sound wave) propagated by the elastic compression of the medium |
| transparent | having the property of transmitting light without appreciable scattering so that bodies lying beyond are seen clearly |
| ultraviolet | situated beyond the visible spectrum at its violet end —used of radiation having a wavelength shorter than wavelengths of visible light and longer than those of X-rays |
| amplitude | the extent of a vibratory movement (as of a pendulum) measured from the mean position to an extreme |
| transverse waves | a wave in which the vibrating element moves in a direction perpendicular to the direction of advance of the wave |
| electromagnetic waves | a wave of energy having a frequency within the electromagnetic spectrum. |
| translucent | transmitting and diffusing light so that objects beyond cannot be seen clearly |
| equilibrium | a state of adjustment between opposing or divergent influences or elements (balanced) |
| pitch | the property of a sound and especially a musical tone that is determined by the frequency of the waves producing it :highness or lowness of sound |
| trough | a long, low area between waves |
| disturbance | a local variation from the average or normal conditions |
| opaque | blocking the passage of radiant energy and especially light |
| conductors | a material or object that allows electricity or heat to move through it |
| loudness | the attribute of a sound that determines the magnitude of the auditory sensation produced and that primarily depends on the amplitude of the sound wave involved |
| crest | the highest part or point of the wave |
| refraction | the action of distorting an image by viewing through a medium; |
| insulators | a material that is a poor conductor (as of electricity or heat) |
| electromagnetic spectrum | the range of all possible frequencies of electromagnetic radiation |
| refraction | the bending of a ray when it passes at an angle from one medium into another in which the speed is different |
| energy | ability to cause change in matter |
