Longitudinal Wave….(sound waves)
1. Draw and label this wave in your notebook
2. Now label the wavelength on this wave (hint: wavelength
can be measured from 2 identical areas of a wave)
Warm-Up
 Review your notes…Does light travel
through mechanical or
electromagnetic waves?
 How do you know?
Warm Up: Answers
 Remember, light waves are
electromagnetic waves so they can
travel through a vacuum
(completely empty space)
 Enables sunlight to reach us on Earth!
Homework….
 Get out your homework and trade notebooks with your
table partner or someone near you….
 1. Create a wave (we will review the 7 parts now)
 2. Waves Graphic Organizer (we will review the
information next)
 3. Ed Helper worksheet and Anatomy of a Wave (we
will go over it last)

Transverse Waves….(ocean waves)
Longitudinal Wave….(sound waves)
Which wave has the lowest
frequency?
Which wave has the highest
energy?
Sound waves..
 Remember, sound must have a medium to travel

wave)
Name 3 states of matter that sound can travel
through…
