60 seconds – how do you feel?
High energy and stressed
Or
Low energy and calm
Waves carry Energy!!
Bell Ringer
List as many types of waves as you can in 2 min- GO!
Do the wave what was sued and moved? Did you physically go across the room?
Waves carry ______!
Agenda
1.Bell ringer *Wave TARGET Form staple into new composition book!
**Pre- eval your knowledge and set goals for each target.
2.Waves carry Energy-
2 types of waves and their characteristics chart on board (or worksheet)
Virtual Lab Wave chapter 15-
complete sheet given as we work through the virtual lab.
3. Explain how to do vocabulary:
Students make a 3 Colum chart for vocabulary
word define diagram (several words can be used for one diagram if labeled and neat)
**we learned to use the summary in the book and the on-line text to help)
Reminder 101 text 606-302-9022 code @ed5d5
Homework: Research– site your source and google is not a site!
“How is electromagnetic radiation affecting humans?” Be ready to share on Wed.
1. 2. Copy Board notes on comparing frequency to energy and length of waves- Target 1
velocity of waves=wavelength x frequency
Formula too
Demo the wiggler to show
increase frequency = decrease wavelength
3. Activity How does water (a mechanical waves-)respond to a disturbance? Video clip of water waves mechanics on -line text.
( pan, dropper, beaker, bobber, plastic ruler to press water toward the block; teacher set up glass dish on overhead)
*Use droppers can you make constructive interference? Draw it
*Make destructive interference
*Use ruler to press water toward the block watch for diffraction.
What happens when you move the water harmonicallyslowly verse quickly?
use video clip of water waves, diffraction and interference to help with what is being seen in the resonance,
Harmonic motion (use tuning fork)-CPO book11.1- how to tune into a radio station. Biking Pendulum!

Complete sentences:
Mechanical wave like sound travel ______in solids and slower in the air.
Electromagnetic Waves like light travel at
3x108 m/s, the speed of light in space and ______when they enter our atmosphere or encounter any medium. This is why stars twinkle. Light could travel around the Earth 27 times in a second, that’s fast.
Agenda:
- **calculating velocity of waves-on line student resources or e activity practice one.
- Used the wiggler set up to test our hearing.
- Light virtual lab- light can reflect and refract

Agenda:
- Bell Ringer- calculate the velocity.

Ch 4 virtual lab- formation of photon
- Where does light come from? Dual Model!
Homework : be ready to share Wed!!
“How is electromagnetic radiation affecting humans?”
Title: ______radiation’s affects on humans.
- Bibliography- (can’t say googled it)
- What type of EMR Cause the affect?
- Effects on humans + and -
- Preventionand/or treatments
Where do light waves come from?
Let’s start with Fireworks formation of the different colors.
Chapter 4 virtual lab –(only the photon part)
Where does light come from?
Diagram the stages of Photons (light) being released:
Write the steps:
1. Atom at a Stable level
2. Energy is added by another photon bumping it.
3. Electron “quantum leaps” back to its stable orbit around the nucleus (goes home).
4. Energy as a light photon is emitted (emission spectrum).
Diagram energy added to electrons causing them to be bumped outer orbit then quantum leap back to stable orbit emitting photons.
Then, put the # from the steps to match the stages:
Target 2 Light is it a wave or a particle of photon?
Watch the video clip and make chart or take notes
Video clip:
Dual models of lightas awaveor particle photon!
2 ways light acts like awave 2 ways light acts like a particle “photon”
- It can refract (bend) 1. Travels in space
around objects
2.light disperses 2. Light can reflect off
into their true frequencesand do damage
Rainbow dispersion glassesbuilding window, lightening
Watch Dr Quantum’s video of Dual models of light and quantum leaping.
In the CPO Book read about Einstein’s noble bell prize for observing that different color of lights carry different amounts of energy because their frequency was greater even though they traveled at the same speed.
(Photon particles knocked off metal particles)
How does sun screen work? See article and sample.
Agenda:
1Bell Ringer:Where does light come from?
Use info sheet and yesterday’s notes to help you
2. Draw and define the following:
Dispersion by a prism or drop of water (rainbow)- separates white light into its true colors frequency. Red long wavelength so low frequency and energy.
Blue high frequency waves have high energy and
short wave lengths.
3. View Christmas lights with dispersion glasses.
4. Virtual lab light Ch. 16- You can finish in computer lab
Is light acting like a wave or particle?
Bell Ringer: Watch and sketch an instrument you want to make and share next week.
Why do some notes have a lower toned?
(Wavelength or frequency makes the biggest difference)
Agenda: Bell ringer
- Quiz yourself- “light and wave” worksheet- do without destructive interference (silently)and earn what effort you put into it and with corrections done in red next day to help you focus on areas to study for test next week.
- Use data on table to complete the EMR spectrum
- Compare Electromagnetic waves frequencies to their wavelengths and energy levels!!!
- Einstein’s noble bell prize for observing that different color of lights carry different amounts of energy because their frequency was greater even though they traveled at the same speed. (Photon particles knocked off metal particles)
- Decibel reading of your voice -say your name.
Boys verses girls group decibel level- constructive verses destructive interference.
Went outside to test yelling- Lunch
- Students share:
“How is electromagnetic radiation affecting humans?”

Pay Attention they say!
How? ______
*Pay with practice and patience on how to focus on the moment and not get distracted, destructive interferences.
Write these 3 questions and be able to explain each by the end of class:
- 1. What type of waves are brain waves since they are electrical impulses along axons? Mechanical or Electromagnetic?
- After analyzing the electroencephalogram, explain when your brain is the most active (highest frequency). See handout
- What kind of electromagnetic waves are emitted from your head due to the work you’re doing? Hint you wear a hat to keep heat in.
