14. Exit Ticket:
How do the characteristics of
transverse waves and
longitudinal waves compare

15. 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

17. 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

18. 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.

19. 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
