1 1.New seating chart?? 2.Binders – START SCHEDULES ON A NEW BLANK SHEET OF PAPER!! You MAY take the first semester schedules & assts out, bundle them together, and put them someplace safe at home. (You’ll want them to study for the 2 nd semester final)OR … buy a new binder & keep all handouts/reference 3.Turn in Guided Notes ?? 4.Slinky Minilab … Work in groups of 3 (not 4) on the ground in the aisles, each person fill out worksheet; need to get up to #17 done today Hand slinky to teacher at end of class to check its not twisted together 5.Asst: (note there is an enlargement of the first slide on the back!) packet 1 NOTES and then draw a line and … ANSWER the self-check questions (number them if they are not #’d; there are 10 of them) YOU WILL NOT GET FULL CREDIT UNLESS YOU DO BOTH! Mon Jan 27 START SCHEDULES ON A NEW BLANK SHEET OF PAPER!!

2 Tues Jan 28 1.Collect packet 1 work (questions first) Did you do BOTH notes, drew a line, THEN answered questions too? You will not get full credit unless you did both 2.Waves packet 1 quizpacket 1 3.FINISH Slinky minilab – all of side 2 AND the interpretation questions must be done 4.HW: waves packet 2 brief NOTES, draw line, then.. … ANSWER 18 questions also (Slinky Minilab with interpretation questions *online if you need them* is due Friday) (oopsie: #16 answer = 5.9E-7 not E-9!)

3 Slinky Mini-lab Interpretation Questions 1.What are some major & important characteristics of waves that you have investigated in this minilab? List at least 3. 2.Where in the environment can you observe properties of waves in action? 3.The “wave equation” is v = . (Your book says v = f, but you should learn the use the “nu” which stands for “frequency”. Look at your results for lab questions about speed, wavelength and frequency. Find at least 2 examples which show the relationships in this formula. (ie: if velocity goes up, frequency also goes up, etc.) Write the lab question number, and write out the relationship that question showed, that supports the wave equation. You need at least 2 examples. 4.Sketch the three wave scenarios on the right on your own paper. After the equals sign, draw a single pulse that has the correct amplitude of that split-second meeting. (Why don’t you write in the value of the amplitude also, so it’s clear.) 5.ALSO, for each of the three wave scenarios at right, sketch what they will look like AFTER they are done interacting. (Hint: waves pass through and go back to exactly the way they were before, albeit in a new location.) 6.Finally, for each of the three scenarios at right, tell whether they are constructive or destructive interference.

4 Wed Jan 29 1.Pick 1 partner; 1 of you login to a laptop immediately 2.Collect packet 2 work (questions first – math??) 3.Correct quiz 1, Waves packet 2 quizpacket 2 4.Computers: start “CPU’s” 5.HW (a): waves packet 3 brief NOTES, draw line, then ANSWER questions (# them; there are 16 today) …..DUE tomorrow! 6.HW (b): Slinky Minilab with interpretation questions *online if you need them* is …..DUE Friday! 7.HW (c): Start Earthquake packet notes …..DUE Monday! NOTE that you WILL be able to use anything from your Earthquake notes to answer the Earthquake questions on your waves test! (so do a good job!)

5 Thursday Jan partner logs in immediately 2.Turn in packet 3 work (questions first? – math??) (can you do those MATH problems correctly from both packets 2 & 3?) 3.Correct quiz 2; Waves packet 3 quizpacket 3 4.Computers: CPU’s remember – you should have Doc 1 already saved in your I drive, so open that & keep going 5.HW (a): waves packet 4 VERY GOOD NOTES and then ANSWER the four questions....DUE tomorrow! 6.HW (b): Slinky Minilab with interpretation questions *online if you need them* is …..DUE tomorrow! 7.HW (c): Start Earthquake packet notes …..DUE Monday! NOTE that you WILL be able to use anything from your Earthquake notes to answer the Earthquake questions on your waves test! (so do a good job!) Note, on slide 11, your packet #4 may say: Question: Open up your Physics book to page 304, Applying Concepts #6. Please scratch that out and replace it with this: Question: Open up your Physics book to page 397 #68.

6 Friday Jan partner logs in immediately 2.Turn in Slinky Lab 3.Turn in packet 4 work (questions first?) (can you do those MATH problems correctly from both packets 2 & 3?) 4.Correct quiz 3; Waves packet 4 quiz 5.Computers: CPU’s (remember – you should have saved Doc’s in your I drive, so open that & keep going.) 6.HW: Earthquake packet notes (due Monday) NOTE that you WILL be able to use anything from this day’s asst on your waves test next week!

7 Mon Feb partner logs in immediately 2.Correct quiz 4 3.Turn in Earthquake notes 4.Computers: CPU’s 5.HW: waves packet 5 NOTES & then draw a line & ANSWER 19 questions.

8 Tues Feb partner logs in immediately 2.Turn in packet 5 work … key to packet 5 self-check questions. Collect packet 5 (QUIZ????) 3.Computers: FINISH CPU’s (last day) 4.HW: (see handout; 80 b & 88 you may skip; note important ones listed in pink below!) page 386 #22-25 Page 391 #27 and 29 Page 396 #40-44, 47-48, 50-52, 54-56, 57, 59, 62-66, 68, 75-79, 80 a&c only, 81-82, 84, 89-91, 93, Page 876 # 8 & 9 Page 401 #6 and 8 =43 problems over 2 days (Due Thursday) Also, note some of them are EXTREMELY important: page 396 #57, 68, 79c, 81, 82, 93

9 Wed Feb person logs in immediately?? (need to finish CPU’s?) 2.Grade Quiz 5 3.Go over Slinky lab (correct with red pen) 4.Go over Guided Notes 5.Maybe some time to finish CPU’s ???? when done, work on book problems… 6.HW = FINISH Book problems (note very very very important ones = page 396 #57, 68, 79c, 81, 82, 93) Due Thursday

10 Thurs Feb 6 1.Go over CPU’s (lecture notes) 2.Bill Nye Waves & worksheet (½ hour) Need to make up if absent! 3.Asst: Answer 50 self-check questions quickly WITHOUT looking at any notes, the book, or anything else. This is to be treated like a “pre- test”; unit test is this PLUS the book problems. If you end up having to leave a question blank (or have one you’re not sure about) THEN go back after you're all done with a different color. This will tell you exactly what you need to study this weekend!

11  incident  reflected CPU Sims 1-2 in brief Sim 1, Relationships: –NOTE – you would change amplitude or frequency by changing the source; change velocity by changing water –If medium constant, velocity constant and wavelength & frequency change INDIRECTLY (one increases and the other decreases)... 1st graph in excel –If medium changes, frequency constant and velocity & wavelength change DIRECTLY (either both increase or both decrease)... Graph 2 in excel –Amplitude NOT dependent on anything (vel, wavelength, or frequency), nor can it change any of those.. First data table in Word, last graph in excel Sim 2, Reflections: –Law of Reflection says incidence angle = reflection angle (don’t forget both must be measured from the normal!)

12 CPU Sims 3-4 in brief Sim 3, Depth (changing medium) Effects: –If medium changes, frequency constant and velocity & wavelength change DIRECTLY (either both increase or both decrease)... Graph 2 in excel –If medium changes AT AN ANGLE, then because PART of the wave slows down or speeds up, the wave will BEND. –Notice in middle picture, faster medium has bigger angle. (We will learn the math equation for this when we do Light/Optics.) Sim 4, Diffraction: –Neat pictures of single-slit diffraction & double-slit diffraction (double-slit causes an interference pattern with nodes & antinodes) –Learn: longer wavelengths and/or smaller slits cause more diffraction

13 Fri Feb 7 (copy next day too!) 1.Note about inverse vs reciprocal, and angle measurements 2.Go over … 1.Concepts (57, 84, 87, 91, 6 & 8) 2.Other book problems? 3.50 Self-Check questions (#16, 47, others??) 4.Bill Nye answers (if time) 3.HW – MEMORIZE and STUDY ( if questions!) TEST

14 Mon Feb 10 1.TEST 2.Asst: (a) Guided notes on SOUND chapter 15 3.Need to turn in All (1-50) self-check questions ALL Handouts IT IS EXTREMELY IMPORTANT YOU ARE IN CLASS (ON TIME) THE NEXT 2 DAYS AS WE START SOUND!!!
