Master Sound Waves: Study Guide & Test Prep for Chapters 10-11 & 25-26

Prepare for finals with this comprehensive study guide focused on sound waves and related concepts. Review chapters 10, 11, 25, and 26, complete the test corrections, and finish the POGIL at your own pace. Key homework tasks include reading and studying sections 26.1 to 26.4 and 26.6 to 26.7, and answering specific problems for points. Understand sound wave properties, like wavelength and frequency, and their implications for hearing in humans and dogs. Don't forget the upcoming test dates of May 21 and 22!

  1. Ch 26 Day 1 – Sound May 15 & 16

  2. Do Now:Take back your… - CH 10-11 Test - Ch 25 QuizMake corrections on both! FINALS are soon, and these are your study guide! When done, see me for today’s POGIL – you are working at your own pace today to the bell. Homework: • Read & Study 26.1 – 26.4, 26.6 – 26.7 • Do # 1-12 – 7 points, ½ pt each & 1 pt for correctness • Finish POGIL if needed. **Test May 21 & 22 on CH 25 & 26**

  3. Finish the POGIL!!! • Whatever is not done becomes HW!!! • In addition to this HW: Read & Study 26.1 – 26.4, 26.6 – 26.7 Do # 1-12 – 7 points, ½ pt each & 1 pt for correctness

  4. EXIT: Get a Clicker and Take an Exit SlipHINT – you may need to reference #17 in your Ch 26 POGIL • A bat flying in a room temperature cave emits a sound pulse and receives its echo in 1 second. How far away is the cave wall? 2. A sound travels in room temperature air. It takes 0.03 seconds for one sound wave to occur. • What is the wavelength of the sound wave? • Can a human hear this sound wave? • Can a dog hear this sound wave?

  5. A bat flying in a room temperature cave emits a sound pulse and receives its echo in 1 second. How far away is the cave wall? • Less than 170 m • 170-171 m • Between 171 - 340 m • 340-342 m • More than 342 m • Not enough info to solve.

  6. A bat flying in a room temperature cave emits a sound pulse and receives its echo in 1 second. How far away is the cave wall? • What do we know? • Room temperature air = sound wavespeed of 342 m/s (or 340 if you rounded) • Wavespeed = distance traveled / time • 342 m/s = x/ 1s • 342 m/s = 342m / 1s • Which means that since it was an ECHO, the cave wall is 171 m away! • (travels 171 m there, and 171 m back, for a total distance of 342 m)

  7. Regarding #1, how do you feel? • I have no clue what is going on • I think I’ll be ok with more practice • I did not get this correct the first time, but I know how to fix my error in the future • I got this correct the first time and I know what I am doing sow ell I could teach it to others!

  8. 2. A sound travels in room temperature air. It takes 0.03 seconds for one sound wave to occur. A. What is the wavelength of the sound wave? B. Can a human hear this sound wave?C. Can a dog hear this sound wave? • Approx. 10.2 m • Approx. 33.3 m • Approx. 342 m • Approx. 11,322 m • Correct answer is not listed • Not enough info to solve.

  9. 2. A sound travels in room temperature air. It takes 0.03 seconds for one sound wave to occur. • What is the wavelength of the sound wave? • Can a human hear this sound wave? • Can a dog hear this sound wave? What do we know? • Room temperature air = sound wavespeed of 340 or 342 m/s • 0.03 seconds for one sound wave is the period • Frequency = 1/ period • f = 1/ (0.03)  f = 33.3 Hz (in other words, there are 33 waves per second)

  10. A sound travels in room temperature air. It takes 0.03 seconds for one sound wave to occur. • What is the wavelength of the sound wave? • Can a human hear this sound wave? • Can a dog hear this sound wave? • = 33.3 = 10.2 m

  11. #2 – can a human hear this sound? • Yes • No • Not enough info to solve 33.3 Hz = within Human hearing Range

  12. #2 – can a dog hear this sound? • Yes • No • Not sure 33.3 Hz = NOT within dog hearing Range

  13. Regarding #2, how do you feel? • I have no clue what is going on • I think I’ll be ok with more practice • I did not get this correct the first time, but I know how to fix my error in the future • I got this correct the first time and I know what I am doing sow ell I could teach it to others!
