2. New trial programs to compress our normal period to be 10 min shorter, 48 min of instruction and guided practice instead of 58 min.
5 min for journal every day. When all students finish at least 3 sentence journal, rest of time (hopefully 5 min) will be chill time where you can get out phones, chew gum, etc. Only one rule, cannot get too loud. I predismiss all rows during last 5 min, so you leave with the bell.
1. Test for Ch 4 will be included in Ch 5 Test when Ch 5 finished

Objective: a. Be able to tell where each type of EMR is on the spectrum & their frequencies ( ν ) and wavelengths ( λ ); (b) be able to calculate ν if given λ, or λ if given ν Learning Tasks: be able to tell how ν and λ change with each other. DO NOW Copy and label figure 5.2 top of page 119. CW copy spectrum on bottom of p. 120 all of it, including
labels. If you have colored pencils, you can add the color insert above the spectrum. If you don't finish it is HW.

speed of light = 186,282 miles/secc = λν
= νcλ
ν λ = cwavelength
frequency
divide both sides by ν
divide both sides by λ
