					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
     see your paper. When you are both ready, click to get the actual answer.

   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!

               4.5 times faster in water so v=4.5 x 345 m/s
               Then use v=fl
