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 harmonically slowly verse quickly?

use video clip of water waves, diffraction and interference to help with what is being seen in the resonance,

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:

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 light as a wave or particle photon ! 2 ways light acts like a wave 2 ways light acts like a particle “photon ”

1. It can refract (bend) 1. Travels in space around objects

2. light disperses 2. Light can reflect off into their true frequences and do damage

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

2. 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.

3. Use data on table to complete the EMR spectrum

4. Compare Electromagnetic waves frequencies to their wavelengths and energy levels!!!

5. 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)

6. Decibel reading of your voice -say your name.

Boys verses girls group decibel level- constructive verses destructive interference.

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. 1. What type of waves are brain waves since they are electrical impulses along axons? Mechanical or Electromagnetic?

2. After analyzing the electroencephalogram, explain when your brain is the most active (highest frequency). See handout

3. 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.
