Be sure to write the answers to the questions below in your notebook, in the format specified by the lab sheet.


All wave animations are external links, composed and maintained by other people.  Thank you for making these animations available to students!

Waves are fun to study, because there are so many examples:  sound, water, light, earthquakes, and more.

Answer the following questions in your notebook (pg. 39-40).

1.  Copy into notebook:  "Wave--rhythmic disturbance that carries energy but not matter"

Describing waves

2.  Click on the crests & troughs picture and draw this diagram in your notebook.

Go to the frequency animation, and play around with it. 
3.  Use what you see to write your own definition of frequency in your notebook, which can include diagrams.

Go to the amplitude and wavelength animation, and play around with it.
4. 
Use what you see to write your own definition of amplitude in your notebook, which can include diagrams.
5. 
Use what you see to write your own definition of wavelength in your notebook, which can include diagrams.

Types of Waves
There are 2 main types of waves:  transverse, and compressional (a.k.a. longitudinal).

Go to the wave motion page, and watch the animations of compressional and transverse waves.
6.  Using a complete sentence, list one thing that is similar between compressional (a.k.a. longitudinal) and transverse waves.
7. 
Using a complete sentence, list one difference between compressional (a.k.a. longitudinal) and transverse waves.

Go to the red dot page, and use it to answer # 8 and #10.  Notice that you can click between transverse and longitudinal.

8.  In your notebook, draw the following diagram:arrow
   
Start the animation for the transverse wave.  Carefully watch the red dot.
    To the diagram you already drew, add a short line with arrows on both sides that shows the movement of the red dot.

9.  Copy into notebook (include the picture):  "Transverse wave--a wave where the particles move perpendicular to the direction
                                                                    of the wave.  Example:  water waves transverse wave drawing"

10. 
In your notebook, draw the following diagram:arrow
   
Start the animation for the longitudinal wave (you have to click the button to change it).  Carefully watch the red dot.
    To the diagram you already drew, add a short line with arrows on both sides that shows the movement of the red dot.


11.
  Copy into notebook (include the picture):  "Compressional wave--also known as a longitudinal wave--wave where the particles move parallel to the direction of the wave.  Example:  sound waves diagram of compressional wave"


Go the the earthquake wave website, and play the animations.
12.  Answer in a complete sentence:  What type of wave is a P-wave (transverse or compressional)?
13.  Answer in a complete sentence:  What type of wave is an S-wave (transverse or compressional)?

When you are done with all the other questions, check out this visualization of different wavelengths of sunlight.
Sunlight is an electromagnetic wave, which is like two transverse waves combined at right angles to each other.
Scroll down on this page to see an animated model of how electromagnetic waves move.
