Today we are doing a fun little activity with resonance...Mary Had A Little Lamb...to be explained in class.
After completing the activity time will be given to complete the assignment due today and the other resonance problems.
Today we are completing the standing waves investigation and starting the unit assignment. The assignment can be downloaded below...
Today we are doing the standing waves investigation (vibrating slinky, fixed at both ends). The investigation sheet is in the package that was posted a few days ago (and was distributed in class).
Here are two video overviews from a few years ago (2011) showing this investigation and with a brief lesson - video 1 is the experiment and video 2 is the lesson..watch both.
Today is a work period. You will complete the EXAMPLES (1,2 and 3) and PROBLEMS (1-5) from the standing waves package. Include diagrams and show all work.
What are standing waves and how do they form? The applet below is a great tool for understanding how standing waves are formed when periodic waves reflect back and interfere (constructively and destructively) with themselves; the result is a standing wave.
Today we will continue work on the Doppler Effect and work on some review - just to get back up to speed (ha) after the break. Our next topic will be Resonance (looking at the concept as well as how it relates to musical instruments, architectural design and construction, etc.)
Today we will be learning about the Doppler Effect. Watch the video tutorials below and complete the notes part of the package as well as the example problems. In class we will do a quick recap of the lesson, talk about applications of this (doppler radar, the big bang, police radar, etc.) and work on the problems.
Lesson - the doppler effect
Watch the video - take notes from the lesson in your package (including the examples) - also watch the video after this one.
basics of the doppler effect
Today we are doing three major things...
