2. Why does Dr. Darden’s group study waves in the water?

3. What are waves? What causes waves? How do waves travel? ◦ Based on the demonstration with the duck in the water answer the above question as a group. ◦ Explain what you think the process involves: ◦ Think about it- Hypothesize You MAY NOT use your textbook at this point.. * Remember that any moving object has energy*

4. Vocabulary- Section 1 Waves ◦ Medium ◦ Mechanical Waves ◦ Energy ◦ Vibration ◦ Waves ◦ Disturbance Define these terms- You may need to use a dictionary along with your textbook Then try to apply these terms to your answers to the questions What are Waves? What causes waves ? How do waves travel?

5. What are waves? What causes waves? ◦ A wave is a disturbance that transfers energy from place to place… ◦ A moving object has energy – my hand transferred energy to the water ( medium)… ◦ This caused a disturbance in the medium (water) which sent a vibration- an up & down or back and forth motion through the water… ◦ Creating a wave in the water

6. How do they Travel? Mechanical waves- require (need) a medium to travel through. ◦ A medium is material that a wave travels through- ◦ Solid( Rope), liquid (Water), or Gas (air). ◦ Waves travel through the medium- waves DO NOT carry the medium along with it..

7. ◦ Where do waves get their energy from? Or ◦ Write something that stuck with you today. ◦ Posit it on the

16. May 26, 2015 Homework: Complete pg. 122 notes if not done in class Do Now: ◦ Agenda - Write H.W ◦ Update T.O.C pg. 122 Types of waves ◦ Open T.B to pg. 16-17- Read then define and describe the three wave types on pg. 122

17. Types of Waves ◦ Transverse ( means across)- Waves that move the medium at right angles to the direction of motion. Longitudinal- move the particles of the medium parallel to the direction of motion. Ex. Coils of a spring

18. Types of waves continued… ◦ Surface Waves- Combination of transverse and longitudinal waves. ◦ Occur at the surface between two mediums ( air and water) ◦ Both the up and down motion of a transverse wave and the forward and back motion of a longitudinal wave.

19. Create Wave Models ◦ Use provided materials to create models of Transverse and Longitudinal waves. ◦ Models should identify wave parts as well ◦ **Hint **use the textbook if your stuck for ideas ◦ A pencil may be helpful to help in creating a longitudinal wave. ◦ Diagram and label the parts of your model ◦ Include arrows showing the directions of motion of the waves and the particles of the wave.

20. What type of Wave is it- Name its parts 1 2

21. May 27, 2015 Homework : Complete Pg. 125- Read T.B pgs. 18- 21 for help. Do Now: ( You have 8 Minutes) ◦ Agenda- Write H.W ◦ Update T.O.C pg. 123 Anatomy of a Wave 124 : Amplitude and Wavelength ◦ Get Lab journal from bin. Update T.O.C pg. 21- Wave Properties ◦ Complete pg. 123-

22. Wave Properties---Wave Length- Distance between two matching parts of a wave. Transverse Waves Measure distance from- - Crest to crest or - Trough to trough

23. Wavelength- Longitudianl Waves Measure from Compression to compression

24. Amplitude- ◦ The measure of how much a particle in a medium moves, from its rest position, when disturbed by a wave. ◦ Transverse Waves The farther a medium moves, above or below the rest position, the greater the amplitude.

25. Amplitude- How compressed or rarefied the medium becomes— High vibrations cause very crowded compressions and very loose rarefactions.

26. Complete discover activity on pg. 18 Answer these additional questions: Measure the wavelength of the wave Measure the amplitude 1)What could you do to increase the amplitude of the wave? To make it larger? 2) What do you think would happen to a longitudinal wave during this test? 3) What connections can you make from these observations? How do you think the amount of energy involved is related to a wave’s amplitude?

28. How are amplitude and energy related?

29. What stuck With you??? How much energy would you need to create a larger amplitude? A high amount or A low amount How do you measure amplitude of a transverse wave?

30. Create Wave Models ◦ Test your model: 1)What could you do to create a larger wave? A smaller wave? ◦ What were the motions of your hand? ◦ What amount of energy did this take? How could you tell?---explain 2) How did these different motions effect the wave? ( its size, how did the parts of the waves change?) 3) What do you think would happen to a longitudinal wave and its parts? 4) What connections can you make from these observations? (How do you think the amount of energy involved and your observations are related?)

35. Frequency - measured in hertz (Hz) ◦ What happened when you moved the string faster in a second? ◦ What happened when you moved the string slower in a second? ◦ Measures the amount of waves (crests) that pass a point in a given time.

36. Waves with the same speed can have different frequencies because________________________________________________.

37. Speed ◦ Measures how far a wave travels in a unit of time. ◦ Different waves travel at different speeds, for example light and sound. ◦ Speed of light is ~300,000,000 m/s ◦ Speed of sound is ~340 m/s Speed = Wavelength x Frequency
