Cards in this deck (15)
- 1wavestransfer energy + information without tranferring matter
- 2oscillationsperiodic motions at a certain frequency
- 3mediumthe substance, material or vacuum that a wave travels through
- 4transverse wavesthe oscillations are perpendicular to the direction of energy transfer
- 5longitudinalthe oscillations are parallel to the direction of energy transfer
- 6compressionareas of high pressure/concentration in a wave
- 7rarefactionareas of low pressure/concentration in a wave
- 8frequencythe number of complete waves passing a point per second
no. of waves / time - 9time periodthe time taken for a complete wave to pass a point
1 / frequency - 10wavespeedspeed at which the peaks of the wave travel
distance / time
frequency * wavelength - 11primary waves-longitudinal
-faster
-travels through solids/liquids
-|||||| - 12secondary waves-transverse
-slower
-only travels through solids
