2)  Study for QUIZ on Light

Quiz Dates:

Block I: next Tuesday, Jan. 17

Block II: Friday, Jan. 13

Block III: next Wednesday, Jan. 18

Here’s what you need to know for the quiz:

• What are the wavelength, amplitude, and frequency of a wave?
• The Electromagnetic spectrum- Which types of waves have lower/higher energy?  (You don’t need to memorize each type, but you need to be able to explain which types have a higher/lower energy based on their frequency.)
• Colors
  • How do pigments work?
  • How do filters work?
• How to measure angles of incidence/reflection.
• How to predict the path of a reflected ray.

This analogy can be useful:

The observer sees the fish above where it actually is because the light reflected off the fish is refracted when it moves from the water to the air to the observer's eyes.

Here’s a clear explanation of how rainbows are formed with refraction:

*******************************************************************

Diffraction occurs when light bends around barriers or through openings.

This is what you saw in class and why:

The diffraction grating has tiny scratches in that the light bends around. Different wavelengths will bend at different angles which separates the white light.

********************************************************************

Polarization

Light waves are transverse waves that when they are unpolarized, the waves move up and down in many different directions.  Polarizing filters have small slits that allow only the light waves that are oriented in the right direction to pass through.

This is a cool demonstration with polarizing filters and clear tape.  Light travels through the tape at different speeds (caused by refraction) and then travels through the filter which polarizes the light.

Check out this link from the Exploratorium for a clear explanation of how rainbows are formed.

2)  Complete HW# 13: Over the Rainbow

*You will need a protractor to complete the homework.  Please ask if you need to borrow one.

Due date:

Block I: next Monday, Jan. 9

Block II: Friday, Jan. 6

Block III: next Monday, Jan. 9

*************************************************************

3)  Complete Science Fair Experimental Plan or Invention Design Plan

*I’m handing these out early this week so don’t freak out and say you only had a few days to do this!!!

**************************************************************************

Musical Notes:

“Over the Rainbow” is the classic ballad song from the 1939 movie, The Wizard of Oz.  It was originally sung by actress Judy Garland.  Here is my favorite version sung by Israel Kamakawiwoʻole, a famous Hawaiian musician, in which he creates a medley of “Over the Rainbow” and “What a Wonderful World.”

Your brains should be well-rested to return to some brain-twisting curriculum.  We’ll be back at full speed…learning about how mirrors and lenses work as well as getting your Science Fair/ Invention projects going!

2)  Complete HW#12: Rearviewmirror

Due date:

Block I: Wednesday, Dec. 14

Block II: Tuesday, Dec. 13

Block III: Monday, Dec. 12

******************************************************************

THE END OF THE GRADING PERIOD IS THIS FRIDAY, DECEMBER 16!
