Tuesday/Wednesday night

Due Thursday for everyone:

Waves and Sound practice.

Reminder that we will be going outside on Thursday.  Dress accordingly.

Monday April 27

All sections-Finish up the Wave Properties Part 2 packet.

The Doppler Effect

Galileos and Einsteins, Thursday:

I am home with my son who is sick.  Please look in the Waves folder for lecture slides on The Doppler Effect, and fill in the notes on "Notes to go with Doppler Effect."  You should also review these images and animations below.

Imagine each of these dots is bobbing up and down on the surface of water, creating waves.

The dot on the left is does not move side to side as it bobs.  The dot on the right moves right.

Here's another view:

Now observe what happens to the frequency in front of the source vs. behind the source.

A similar effect can happen with sounds waves:

In the beginning the engine of the car is making sound, but the car is stationary.  Any observer would head the same pitch (frequency) sound.  Once the car starts moving to the left, the sounds waves to the left (in front of the car) are compressed, and the waves to the right (behind the car) are stretched.  How would an observer in front of the car hear the engine, compared to one behind the car?

Google a video of the Concorde producing a sonic boom.

No homework over vacation...have a nice break!

Same HW Wednesday night

If you didn't finish last night's HW, or if you did it and had questions, or if you did it and DIDN'T have questions but its a good idea to review...do Qs 1-8 on the wave calculation worksheet.

Pretend it's a test!  Show your work!  Include units!  Who knows, maybe there will be a quiz coming up!

Monday/Tuesday night

First night of Waves HW:

Use the "Slides on Waves and Vibrations Properties" document to complete question 9-17 on the "Waves Calculation Worksheet."  Then complete the second half of "Waves Calculation Worksheet," using the equations from the lecture slides.

Due Wednesday for everyone.

Magnetism reading Day 2

Weekend HW:

Read Ch 36 pp 568-571 AND Ch 37 pp 577-579. (Ch 37 is a separate document.)   Please answer Qs 10-15 on pp 575-576. 

Inducing a current using a magnet

Magnetism Reading

Wed/Thur night HW, due Friday

Read pp 562-567 in Hewitt, Ch 36: Magnetism (in the Electric Current folder), and answer Qs 1-9.  Turn your answers into your folder when done.

Weekend HW

HW is to do the Circuits study guide.  Test will be on Tuesday, including a practical.

Reminder that all Q3 work is due today! yesterday!

Answer key will be posted Monday mid-day.  Completed study guides should be turned into your folders by 1pm on Monday if you want to qualify for test corrections.

Posted now: A handy-dandy guide (with pictures!) on how to use the multimeter, which you will need to use on the practical.
