Fourier Waves

2011-01-18T10:01:00.000-08:00

Explain qualitatively how sines and cosines add up to produce arbitrary periodic functions.
Recognize that each Fourier component corresponds to a sinusoidal wave with a different wavelength or period.
Mentally map simple functions between Fourier space and real space.
Describe sounds in terms of sinusoidal waves.
Describe the difference between waves in space and waves in time.

Prnt the worksheet here

Go through the reading http://www.physicsclassroom.com/Class/waves/u10l1a.cfm (there are actually 7 screens that cover Lesson 1 and 2)

Draw a wave and its parts

Summarize what you have done.

Types of Scales

2011-01-10T09:54:00.000-08:00

Tell me how scales work, and how it is related, or NOT related, to Hooke's Law. A quick search on Google Images shows me scales of justice, dial scales, doctor scales, fishing scales and digital scales. Pick 3 of these. Show me for each....a) how it works b) how it is/is not related to the material covered thus far and c) how accurate you believe it to be and why.

Good luck

The Math of Hooke's Law and the Pendulum

2011-01-07T09:51:00.000-08:00

http://www.physicsclassroom.com/class/energy/u5l1b.cfm

You need to copy the formulas into your front cover and then complete the worksheet. Each problem MUST have a drawing, variables circled, and a formula /work to receive credit.

Worksheet

Pendulum Problem

1) what variables affect the period of a pendulum? Explain how you know this from your lab.

2) design a pendulum that has a period of exactly one second on Earth, and one second on the Moon. To do this, you will need to find the formula for a pendulum and create a drawing, variable set, and formula work.
