How do the characteristics of transverse waves and longitudinal waves compare

Answer:

Both waves transmit energy. – Transverse waves can travel through empty

space or a medium while longitudinal waves require a medium to transfer.

– In a Transverse Wave the energy travels perpendicularly to the wave

– In a Longitudinal Wave the energy travels parallel to the wave

Essential Learnings

Transverse Waves – Energy travels perpendicular to the

wave– Do not require a medium– Amplitude is the distance from the

rest position to the crest or trough of the wave.

– Light travels in Transverse Waves

Essential Learnings

Longitudinal Waves – Energy travels parallel to the wave– The portion of this wave where it is

crowded together is called the compression

– The portion where the space between compressions is greatest is called the rarefaction.

Essential Learnings

Longitudinal Waves – Requires a medium– Wavelength is the distance from one

compression to the next compression of the wave.

– Sound being produced by vibrations travels in Longitudinal Waves
