G4 T3 L1 Week of March 8
Objective: I can describe how does a wave move.

4
Transverse wave
A wave that is moving perpendicular to the particle's motion.
The crest is the high point and the Trough is the low point.
5
Longitudinal wave:
the wave that moves in the same direction as the particles.
Longitudinal wave compress and expand as they move.
6
Notebook activity
1-Answer the question in the picture.
2- What is the difference between the transverse wave and the longitudinal wave?

Wave Energy
Waves are a transfer of energy.
If you send a wave along with a spring, you will see the coils move back and forth.
The coil return to its original position after the wave has passed.
10
Transfer:
To change or move from one object to another.
Waves transfer energy through a medium but don't transfer the medium particles.
11
Wave Energy
That's why an anchored boats move up and down when waves passed under them, they are not pushed to the shore.

Notebook activity
Draw in your notebook Wave Q and S
1- Label wave crests, wavelength, and amplitude
2- which one has high frequency?
3-Which one has the highest amplitude ( Q or S)?
