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,

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:

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.

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.

electrical impulses along axons? Mechanical or
Electromagnetic?
After analyzing the electroencephalogram, explain when
your brain is the most active (highest frequency). See
