Week 32 Announcements - You made it to the end!!!Updated May 8, 2022
This is your class landing page, you will want to come here every week to check for any class announcements. Make certain you read everything on this page and understand completely all the directions. You can access past weeks announcements in their respective Quarter pages. Week 31 SummaryThis past Tuesday we started Chapter 18 - Harmonic Motion, by discussing the properties of period (T) and frequency (f) with respect to objects experiencing harmonic motion, and oscillating systems. Recollect that the period of an oscillator is the time it takes for it to complete a cycle of motion, and the frequency involves how many cycles are completed in one second of time, having the units of Hz.
On Thursday, since I did not have enough working radios to carry out the Audio Speakers Laboratory, we instead in class worked on Skill & Practice 19A - Waves, and 19D - Waves and Energy. Test covering Chapters 15, 16, & 17
As already discussed, I emailed your parents the exam covering Chapters 15, 16, and 17 on April 30th. This is due this coming Tuesday, May 10th. As usual, this is a closed-note, closed-book, closed-smart-mom-dad-aunt-uncle-sister-brother-good friend exam. All you need to complete it is the following:
On Thursday you will have a Final Quiz covering only what we discussed in the Skill & Practices for Chapter 18 and 19, the Audio Speaker lab, and the Optics Bench lab. What to expect in Week 32On Tuesday, we will learn how audio speakers work, by working on the Audio Speakers Laboratory. Generally, they are similar in concept to electric motors in that the system depends upon an electromagnet and permanent magnet, but in the case of an audio speaker, electrical energy is translated into sound (mechanical) energy. The speaker itself becomes the medium by which we hear the sound.
On the last day of school you will all carry out a laboratory using an Optics Bench kit. The function of the lab will be for you to just play around with optics - nothing too serious for the last day of school.
