2. Unit 3: Behavior of Light Quiz: Friday April 13th
Intro to Optics
Miss Virga

4. WARM UP 3/21/18
Learning Target:

Warm Up Question:
Four food coloring dyes absorbance's spectrum are shown. Which line represents blue food coloring?

5. shiny and smooth
perpendicular
Angle of incidence 𝜃
Reflection
𝜃 = 𝜃’

6. angle

7. Retroreflectors were placed on the moon!

10. Mirrors – How are they made?

12. For the rest of class, work on Assignment #1
If you finish during class, turn it in to the class bin, and be sure to get a stamp from Miss Virga in your blue packet!
If you do not finish during class, then it is homework! Miss Virga will do a HW check at the beginning of class tomorrow.

13. WARM UP 3/22/18 Learning Target: I can draw a light ray diagram.
I can verify the Law of Reflection using evidence from an experiment.
Warm Up Question:

14. How do one – way mirrors work?

15. Each group of 2 will need…
A mirror
Two binder clips
A piece of white paper
Ruler

16. WARM UP 3/26/18
Learning Target: I can identify the angle of refraction. Warm Up Question: 1. What happens when light enters a medium? a) nothing b) it changes speed c) it reflects d) it bends e) both b) and d)

17. absorbed
refracted
transmitted
Light traveling through the air hits surface of pond; some of the light is reflected, most of it is transmitted!

18. bending
speed
the fastest

20. Phenomena
Observe a pencil setting in a beaker half full of water. Draw what you see when the pencil is placed:
In the center of the beaker
Left of center
All the way to the left

21. Agenda for rest of class:
Complete and turn in Lab #3 (Pencil in Water)
Use any time remaining to:
Finish Lab #2
Finish Lab #1
Work on Assignment #2 (if you finish this as well, be sure to turn it in and get a stamp from Miss Virga in your blue packet!)

22. WARM UP 3/27/18

HW CHECK:
If Assignment #2 is finished, turn it in to the class bin and get a stamp from Miss Virga!

23. index
slower
diamond

24. Refraction

25. Agenda for rest of class:

HW:
Turn in Permission Slips!!!!

33. Fiber Optics

34. Rest of class… Finish Lab #4

Warm Up Question:
Sign up for Remind if you have not already done so:
Text this message:

To this number:
81010
HW:
Turn in Permission Slips!!!!

42. Field Trip to RIT tomorrow!
The bus will leave at 10:30 from the front of the school
Meet in the main doors at 10:15!
Pizza lunch will be provided, if this doesn’t sound good to you than feel free to pack your own lunch!

43. refracted
reflected
refracted
Each color of light slows down differently (each has a unique index of refraction – n)

44. The 2nd reflection reverses the colors b/c there are 2 reflections, and the rainbow is therefore dimmer
