If the frequency of a wave increases what will happen to the
length of the wave?
Answer
Demo the wiggler to show increase frequency = decrease wavelength
Comparing frequency to energy and length of waves- velocity
of waves=wavelength x frequency

60 seconds Silently Deep Breaths!!
Bell Ringer –lets reflect on the year.
Mid- terms are Thursday and Friday so as a gift you get to
silently, No compressional, waves do an open review test
which comes from past reviews and your composition
book!
50% of exam grade is a completed review and 50% is the
test score. So you start the test with a 50% and get to use
the review on the exam.
50% review + 50% exam = 100%
Finished review must be turned in before test.
Mid- term counts 5% of the 9weeks grade!

Happy New Year where do Fireworks light waves come
from?!
Ch 4 virtual lab- formation of photon
Where does light come from? Dual Model!
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
Rainbow dispersion glasses
building 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
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!!!
