Waves
Vocabulary
 Wavea disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy |  Mediumthe material that a wave travels through |  Amplitudethe maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. Ex. Volume |
|---|---|---|
 Wave Lengththe distance over which the wave's shape repeats |  Frequencythe number of occurrences of a repeating event per unit time Ex: Pitch of a sound |
Day 1: Waves
Waves are a unique way that energy is transfered from location to location. This assisnts in the transfer of both light and sound. There are some very unuall thing that occur to solid objects when they are exposed to certian wavelength. Watch the video below to see what happens to a bridge.
This is what happens when a structure is exposed to its own resonce frequency.
Day 4: Sound
Starter Questions:
1. Name the Highest and lowest frequency of light
2. Look at the Waves below
What changed?
A. Aplitude
B. Frequency
C. Wave length
D, Both A & B
E. Both B & C
F. Nothing
He turns a piano into another instrument
Almost anything can be used to create music. Check out these glasses and how the differnt sizes have their own pitch.
Day 2: Light
Starter Questions:
1. What must a wave have to travel?
2. How do we detect a change in amplitude?
3. What is the highest frequesncy of light that our eyes can detect?
In Class Assignment:
The read the following article and answer the questions:
Article : Li-Fi faster than Wifi
Questions:
1. What is Li-Fi?
2. Why would the type of light make a difference?
3. Why wont this technology work out side?
4. Why is this not widely used?
Day 3: Waves Labs
Starter Questions:
1. Which wave has greater energy? One with a small amplitude or a large amplitude?
2. How can our ears detect a change in frequency?
Today we looked at several different ways that waves can be generated. This included having the waves travel though mediums like wood, metal and paper towels.
I have included the link for a tone generator so that you can see what each wave looks like.
Here is a video of the wave tube we did in class
Watch to see how the length of the pipe changes the pitch of the sound created
Check out the PVC pipe xelephone they use to play the song.
