    Problems: 23, 24, 25, 26, 28, 29cd, 30a

**If you forgot to get the frequency of your tuning forks yesterday, use 450hz and 288hz**

**Lab due Friday**

WARM-UP:

1. what happens to light's path when it strikes particles which are smaller than it's wavelength?

2. 1 nm is 1 nanometer, which is 1 billionth of a meter, or 1x10-9m, or 0.000000001m

3. The acronym ROYGBIV is used to help order the relative wavelength of colors of light. Red is ~650nm, and Violet is ~420nm. 

    a. Does the order go from low to high, or high to low?

    b. Would it make sense for Green to be 670nm? Why?

CLASSWORK: 

071A and B: Slideshow link ----->LINK

HOMEWORK

070B: Periods 1, 2, 3, 6, finish the slideshow. Draw the flame, label the hottest and coldest parts/colors. compare those to the wavelengths for each color. Is there a similarity?

070C: To prepare for tomorrow's class, read: http://www.physicsclassroom.com/Class/light/u12l2a.html

            Take notes, and answer the three questions

***Quiz on sound waves & waves/musical instruments & EM waves Monday.
