1Monday, February 23rdEntry Task Blast from the past!!! What are the two kinds of earthquake waves you learned about last year?Schedule:15.1 Notes15.1 RSGObjective: I will compare and contrast transverse waves and longitudinal wavesHomework:Read pagesPlease have on desk:Journal open to vocab, sharpened pencil
2Tuesday, February 24th Entry Task Explain how all mechanical waves are similarSchedule:Review 15.1Wavelength, Frequency and AmplitudeObjective: I will calculate a wave’s speed, frequency, and wavelengthHomeworkRe-read pages Do you know the material?Please Have on Desk:Journal, sharpened pencil
315.2 Notes Waves have Measurable Properties Waves have measurable properties like height and speed.The CREST is the highest point of a wave.The TROUGH is the wave’s lowest point
415.2 Notes Waves have Measurable Properties AMPLITUDE - the distance between a wave’s resting point and the crest or troughAmplitude indicates how much energy a wave is carrying.WAVELENGTH- the distance from one CREST to the next CREST.
515.2 Notes Waves have Measurable Properties FREQUENCY- Number of CRESTS (or troughs) that pass a given point every second.WAVES have measurable properties.
7Waves have Measureable Properties What are 3 main differences between Tsunamis and normal ocean waves? Use vocab. from
8Waves have Measureable Properties What are 3 main differences between Tsunamis and normal ocean waves? 1. Different forces create Tsunamis 2. Tsunamis have longer wavelengths 3. Tsunamis transfer more energy (have higher amplitudes near shore)
9Wednesday, February 25thEntry Task Draw a wave and label: - crest - trough - amplitude - resting point - wavelengthSchedule:Investigate Frequency LabObjective:I will explain how frequency and wavelength are related.Homework:Completed lab handout due tomorrowPlease have on Desk:Pencil
10Thursday, February 26thEntry Task Would the relationship between wavelength and frequency in your lab change if you changed the amplitude (starting angle)? Explain why or why not.Schedule:15.2 math practice15.3 notesObjective:I can calculate wave speed, frequency, and wavelength using theHomeworkRe-read pages 504 – 508.Please have on Desk:Frequency lab, pencil, textbook
11Math PracticeA wave with a frequency of 14 Hz has a wavelength of 3 meters. At what speed will this wave travel?
12Math PracticeThe speed of a wave is 65 m/sec. If the wavelength of the wave is 0.8 meters, what is the frequency of the wave?
13Math PracticeA wave has a frequency of 46 Hz and a wavelength of 1.7 meters. What is the speed of this wave?
14Math PracticeA wave traveling at 230 m/sec has a wavelength of 2.1 meters. What is the frequency of this wave?
15Math PracticeA wave with a frequency of 500 Hz is traveling at a speed of 200 m/s. What is the wavelength?
16Math PracticeA wave has a frequency of 540 Hz and is traveling at 340 m/s. What is its wavelength?
17Math PracticeA wave has a wavelength of 125 meters is moving at a speed of 20 m/s. What is it’s frequency?
18Math PracticeA wave has a frequency of 900 Hz and a wavelength of 200 m. At what speed is this wave traveling?
19Math PracticeA wave has a wavelength of 0.5 meters and a frequency of 120 Hz. What is the wave’s speed?
20Math PracticeRadio waves travel at a speed of 300,000,000 m/s. WFNX broadcasts radio waves at a frequency of 101,700,000 Hertz. What is the wavelength of WFNX’s radio waves?
21Wave Behaviors Read pg 504-508 Identify the 5 different wave behaviors and write them on your notes sheetDefine, give examples (draw pictures to help you) and explanations. Do NOT just copy the book!
22Wave Behaviors Reflection When a wave hits a medium it can’t go through, it bounces off that mediumIt is the reason we see ourselves in a mirror, see colors and hear an echo.
23Wave Behaviors Refraction When a wave hits a new medium it slows down or speeds up, this causes the wave to bend.It is the reason things look bigger or out of place when you look at them through water.
24Wave Behaviors Diffraction When a wave hits a barrier that has an opening, the wave spreads out after it goes through the openingIt is the reason you can still hear someone talking in Mr. McWhirter’s classroom, even though there are barriers between us.
25Wave Behaviors Constructive Interference When waves meet and the result is a wave with a higher amplitudeIt is the reason surround sound works. Sound waves meet and create a fuller, richer sound.It is also the reason that innertubing behind a boat can be so fun
26Wave Behaviors Destructive Interference When waves meet and the result is a wave with a lower amplitudeIt is the reason a stereo may be loud in one part of the room, but quiet in another part. Sound waves meet and create a quieter soundNoise canceling head phones also work because of this behavior of wave
27Friday, February 27thEntry Task Describe what happens when waves diffract. Turn your journal in to the side counter.Schedule:15.2 QuizWaves summaryBill Nye “Waves”Objective: I will reinforce my understanding of waves.Homework:Re-read Chapter 15Please have on desk:Pencil and calculator
