Exit Ticket:How do the characteristics oftransverse waves andlongitudinal waves compare
Answer: Both waves transmit energy.– Transverse waves can travel through emptyspace or a medium while longitudinal wavesrequire a medium to transfer.– In a Transverse Wave the energy travelsperpendicularly to the wave– In a Longitudinal Wave the energy travels parallelto the wave
Essential LearningsTransverse Waves– Energy travels perpendicular to thewave– Do not require a medium– Amplitude is the distance from therest position to the crest or trough ofthe wave.– Light travels in Transverse Waves
Essential LearningsLongitudinal Waves– Energy travels parallel to the wave– The portion of this wave where it iscrowded together is called thecompression– The portion where the spacebetween compressions is greatest iscalled the rarefaction.
Essential LearningsLongitudinal Waves– Requires a medium– Wavelength is the distance from onecompression to the next compressionof the wave.– Sound being produced by vibrationstravels in Longitudinal Waves
