Physics Waves
Cards in this deck (35)
- 1SpeedThe speed of waves measured in mps
- 2FrequencyThe number of waves passing any point per second (hz)
- 3PeriodTime for one complete oscillation
- 4Wave lenghThe distance between any point on a wave and the equivalent point on the next
- 5AmplitudeMaximum distance a point moves from its rest position when a wave passes
- 6transverse wavesa wave in which the direction of the displacement is perpendicular to the direction of propagation
(light wave) - 7Longitudinal wavea wave in which the direction of displacement is in the same direction as the propagation
(sound wave) - 8In reflection..The waves are reflected from the surface at the same angle they strike it
- 9RefractionWhen waves slow, they change direction.
frequency stays the same, slows down, wave fronts close up on eachother, decrease in speed must cause decrease in wave lengh - 10Diffractionwider gaps mean less diffraction
- 11What is the speed of sound?330 ms
- 12Refraction of soundAt night, ground cools quickly, sound waves travel more slowly through cold air, waves leaving ground bend back towards it. bending effect called refraction
- 13100 hz meansoscillating 100 times per second, giving out 100 sound waves per second
- 14Frequency ispitch
- 15Amplitude controls..how loud the sound is
doubling aplitude means 4x much energy per second - 16compressions are regions ofhigh pressure
- 17DiffuseWhen a surface reflects light in all directions
- 18Laws of refraction1. the angle of incidence is equal to angle of refraction
2. the incident ray, the reflection ray, and the normal all lie on the same plane
mirror is laterally inverted - 19PrismSides are not parallel, when light is refracted out it is deviated, splits into range of colors called spectrum, effect called dispersion. red is deviated least, violet is deivated most
- 20critical anglewhen the angle of incidence is greater than the critical angle, there is no reflected ray
- 21optical fibressee heeat
- 22optical fibres is medicinsee sheet
- 23Ways to describe an imagereal/virtual, inverted/upright, smaller/larger
