GUIDES
1 Light Examples
Definition of equations, explanation of equations, worked out example problems.
2 Making Waves 5
Step-by-step illustration of how electromagnetic waves are formed.
3 Electromagnetic Spectrum
Description of how electromagnetic waves are made, why they propagate at a particular speed, how different wavelength/frequency ranges are different from each other.
4 Reflection
Specular and diffuse reflection are distinguished; the law of reflection is developed.
5 Refraction Analogies
Toy axle, life guard; the principle of least time is discussed.
6 Refraction Math
Snell's Law illustrated.
7 Indices of Refraction Reference
Reference chart on indices of refraction.
8 Total Internal Reflection
Description and explanation of total internal reflection. Includes derivation of the equation for critical angle.
9 Atmospheric Refraction
Description of gradual atmospheric refraction and an explanation of mirages.
10 Dispersion
Explanation of dispersion.

1
Electromagnetic Spectrum
This is an in-class research activity. Students use textbooks, reference posters, and the World Wide Web (if available) to assemble data and application info regarding the EM spectrum.
2 Reflections I Lab Springboard
A discussion lab activity to investigate plane reflection using ray box optics.
3 Diversion Into Refraction I Lab Springboard
A discussion lab activity to investigate refraction using ray box optics.
4
Coin in the Cup Lab Springboard - Presentation (Zipped QuickTime)
A discussion lab "magic trick" involving refraction.
5
Index of Refraction Springboard - Answers - Presentation (QuickTime)
A classroom discussion to clarify the meaning of the index of refraction.
6
Critical Angle Lab Springboard - Presentation (QuickTime)
A discussion lab activity to investigate total internal reflection and critical angle.
7
Mirage Tank Lab Springboard - Presentation (QuickTime)
A discussion lab activity to investigate gradual refraction (the phenomenon underlying mirages).
8
Dispersion Diversion Lab Springboard - Presentation (QuickTime)
A discussion lab activity to investigate dispersion using ray box optics.
9
Understanding Rainbows Springboard - Answers - Presentation (QuickTime)
Explaining how a rainbow is formed, I mean really explaining it is among the most difficult things to do in a physics class. The physics is easy; the geometry is tough. This is a classroom discussion designed to explain how rainbows are formed.



LABS
1 Mirror Misunderstandings - Sheets
Thorough inquiry into the nature of reflection from a plane mirror. Deals with the location of a reflected image, the length of the shortest mirror needed to see a complete image, what the mirror reverses and what it doesn't reverse (such as left and right). Thanks to Dewey Dykstra!

Light Begins With an M - Presentation (QuickTime)
Part of the "Physics Begins with an M" series. Make a transperency and put it on the overhead on the first day of the unit to enhance curiousity in the material of the unit.
Light Begins With an M Keynote
A nifty Keynote presentation of the M's. (Keynote is Apple's presentation software; PowerPoint is Microsoft's presentation software.) Trust me, neither Keynote nor PowerPoint are The Great Saviors of education. I recommend using them sparingly if at all. Better to teach!
3 Light Crossword Puzzle Grid - Clues
Crossword puzzles are highly personalized and may not always translate well from my classroom to yours.
4 NEW: PracTest Complete
Note: Question 10 has been changed.

OLD: Practice Test Questions - Answers

Sample test questions covering magnetism and induction.


  OLD 
  Using Snell's Law Lab Springboard - Answers
A discussion lab activity to apply Snell's Law to determine index of refraction using ray box optics.
  Using TIR to Determine n Lab Springboard - Answers
A discussion lab activity to apply total internal reflection in determining index of refraction using ray box optics.
