**If you forgot to get the frequency off 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?

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?
