2. Waves
Draw a standing wave. Label
important terms
(amplitude, wavelength, node, etc)
3. Waves
Compare longitudinal and
transverse waves. Give an example
of each.
4. Waves
Consider how waves are formed in
the ocean. How does a tsunami
form?
Using this information draw some
conclusions about the relationship
between important terms
ex: velocity and amplitude – how are
they related? (Think: what causes the
wave to grow?!)
5. Waves
Define the terms and discuss how
they are related. Also, what are the
units of each?
Wavelength
Frequency
Period
6. Waves
What is the wavelength of the wave
below.
What is the velocity of the wave if
its frequency is 4 Hz?
0.2m
- 0.2m
6m
7. Waves
Student A is on the Huntington Beach Pier
in California and notices 11x World
Champion Surfer Kelly Slater in the ocean
below sitting on his board waiting for a
wave. As a water wave passes, Kelly bobs
up and down, rising to the top of a wave
crest every 10s as he waits patiently for
the perfect wave.
Calculate the frequency of the passing waves.
Calculate the speed of the passing waves.
8. Waves
Student B shakes a slinky to create
a standing wave that looks like this:
5m
What is the wavelength?
If we shake it 3x per second, what is
the speed of the slinky wave?
9. Electricity

voltage?
10. Electricity
Energy transformations!
Where did the energy come from to
light our bulb?
What type of circuit do we need?
11. Electricity
Circuits!
Compare and contrast the two types of
circuits. Draw an example of each.
12. Electricity
What equipment can be used to
measure voltage and current?
How should they be hooked up to the
circuit?
13. Electricity
What do the squiggly line symbols
in our drawings represent?
Define this term.
What is it measured in?
What law helps to define this term.
14. Electricity
Use Ohm’s Law to determine the
relationship between
resistance, voltage, and current. (If
one goes up, what happens to
another?)
What was our other mathematical
equation from Chapter 6?
15. Electricity
An Xbox operating at 240V draws
2A of current. Determine resistance
and power.
16. Electricity
What is the power output of a
Mustang GT with a 12V battery that
supplies a current of 10A to its
ignition?
17. Electricity
A 100W light bulb runs on 200V and
draws 2A of I. Running for 5
minutes (300s), how much energy
is used in this time?
18. Electricity
Draw a parallel circuit with 3
identical light bulbs with a battery
that provides 9V and a current of
3A. What is the current and voltage
for each bulb?
19. Electricity
Draw a series circuit with 3 identical
light bulbs with a battery that
provides 9V and a current of 3A.
What is the current and voltage for
each bulb?
Based on these two answers –
which way are houses wired? Why?
20. Electricity
How do we control all of this
electricity?
What device(s) are used? How are
these different?
21. Electricity
Chapter Challenge Math!
If I use my 100W Hitachi drill for home
renovation work for two hours a
day, how many kW hours do I use in a
day?
*1 kW = 1000W

your answer.
Inducing Currents… “breaking out of
jail” question from the exam!
Which action does NOT produce a
current? Which actions do?
25. Magnetism
List three ways to increase the
strength of a solenoid.
How are a motor and a generator
different?
What happened when I used two hands
cranks in my demo?
26. Magnetism
Think back to our generator
Investigate… what equipment did
we use?
How did we use this equipment to
generate electricity?
