# Waves and Sound Review Jeopardy Game_ 2009-2010

Document Sample

```					Welcome to physics Waves and Sound Review Jeopardy Game
First, person each needs to make a board.  Get a colored piece of paper, turn it sideways and
make a grid that takes up the entire piece of paper that looks like this:

Wave Guts       I love vocabulary!    Sound         Waves in Music   Fun with
Equations!
The test is tomorrow!
It covers all the material- vocabulary, facts, and calculations
from Chapters 12 and 13. Make sure to study!

Please click to read the rules for playing the review Jeopardy game. 

1) Anyone can pick the questions as you are both playing all of the questions.

2) Pick a box and read the clue. You both put your own answer in the form
of a question on your answer sheet being careful not to let the other person

If you get the answer right, write the dollar amount in the appropriate box
and circle it. You can both get it right and get the money.
If you get the answer wrong, put an X through the box. You don’t go negative.

3) If you both get the answer wrong, the money goes to your physics teacher.
Have one person keep a tally for her.  She cannot play the Daily Double or
Final Jeopardy.  If she wins, neither of you get a prize.
4) There is one daily double on the board. You can bet up to as much money
as you have. If you get that question wrong, you go negative whatever
amount you bet.

5) You may or may not finish all of the questions on the board. Near the end
of the hour, it will be time to play Final Jeopardy. For Final Jeopardy if
you do not have any money you cannot play. You can bet as much as you
have, but if you get the question wrong you will go negative.

6) The student with the most money at the end gets a prize . You will both turn
in your Jeopardy board at the end of the hour for up to 3 points extra
credit points towards your test. Make sure to show your work. You will
not earn extra credit for just writing the correct answers if there is a
calculation involved.

7) Make sure you understand how to play! This will help you on the test
tomorrow!

wavelength would have
a) been longer than if the water was cool.

Back to game
What is a) been longer than if the water was cool?
board                                       v=fl
The frequency would be the same. If the water was warmer, the air above it
would be warmer so v would increase meaning that l would also have to
increase.

Squidward to come and catch jelly fish with
him. If the temperature of the water is 76oF,
and the wavelength is 3.78 m, this is the
frequency of Spongebob’s voice.

calculate- double click on this icon:

Click when you are both ready and the box below will
disappear to reveal the correct answer.

What is 411 Hertz?
Back to game   v = 330 m/s + 0.6(24.2oC) = 345 m/s, but sound travels
board
4.5 times faster in water so v=4.5 x 345 m/s
Then use v=fl
Final Jeopardy
Do this on the back of your Jeopardy board.
You each need to make your wager. If you have no money, you cannot play.
If you get it wrong you lose the amount that you wagered. Place your wagers
now. Then click to get the question when both of you have placed your wager.
The category is….Waves and Sound 
An bucket is dropped down a well that is 130 meters deep. This is
the amount of time from when you drop it to when are ready
hear it hit the bottom if it was 10oF. Show your work.
to see the Final Jeopardy question.
(Answer this carefully. Hint- it requires material from a different chapter.)

Click when you are both ready and the box below will disappear to
What is 5.6 seconds?
You need find the time it takes the bucket to fall Dy= viDt+ 1/2aDt2
Then you need to add that to the time it would take for the sound to
come back up which you can find using v = Dx/Dt
Thank you for playing. Total up your money and determine the winner in
your group. The winner gets a prize. 
You both should turn in your Jeopardy board for up to 3 extra credit points
on tomorrow’s test.
