PHYS 2415-002: General Physics II

•  video  - Kinds of Charge and Charging
  (instead of pith balls, balloon electroscope hung from ceiling w/ fishing line / Is it possible to set a camera on the electroscope to project on the screen? )
•  video  - Attraction and Repulsion Between Charged Objects
  (In addition to 2x4, also I'd like to use that bigger prank, too. )
•  video  - Electrostatic Bell
  (on camera )

•  video  - Kinds of Charge and Charging
  (two balloons hung from ceiling w/ fishing line, and a few separate balloons to be attached to blackboard by statics )
•  video  - Attraction and Repulsion Between Charged Objects
  (In addition to 2x4, also I'd like to use that bigger prank, too. Camera possibly. )

•  video  - Electric Fields

•  video  - Van de Graaff Generator

• Whatever Nilanga orders (I have none to think of.)

• None again!

• None!

• Sample capacitors (ordinary blue-cylindrical ones that can be contrasted with the big one used for capacitor discharge)

•  video  - Lightning Rod
  (on camera )
•  video  - Parallel Plate Capacitor
•  video  - Capacitor Discharge

•  video  - Fluorescent Bulb in Faraday Cage
  (I don't need the cage. I just want the bulb to light up near Van de Graaff when it's radially set, and not light up when it's azimuthally set. (Just like Nilanga did today.) I also want some instruction so I won't be zapped during demonstration. )

  (Just want a battery connected to voltmeter and then see the change when current is running (no need to change resistance); on camera )

• Nilanga teaches today

•  video  - Magnetic Deflection of an Electron Beam
  (on camera )
•  video  - Force on a Current Carrying Wire in a Magnetic Field
  (on camera / If Nilanga actually did the demo last time, no need to put it up again )

  (on camera )
•  video  - Galvanometer Movement
  (on camera )
• Electric Motor
  (Just that cute dry battery with cupper loop wires (on DocCam) )

•  video  - Forces Between Current Carrying Wires
  (camera; set up with parallel current first, then I will switch to anti-parallel current (I will try to remember to inspect before my section starts in case Nilanga changes your setup) )
•  video  - Galvanometer Movement
  (on camera )
• Electric Motor
  (Just that cute dry battery with cupper loop wires (on camera) )

•  video  - Back EMF in an Inductor
  ((That gigantic electromagnet with iron bar only: just demonstrating how a chunk of iron turns to become strong magnet by merely turning the switch) )

  (On DocCam )
•  video  - Hanging Ring and Magnet

•  video  - Lenz's Law and Eddy Currents
  (with full disk on (on camera) )
•  video  - Eddy Current Tube
  (set camera from the top of the tube so the falling magnet can be seen )

  (desk top version, with light bulb attached (on camera) )

• No demo (I may use whatever Nilanaga asks!)

• Can Crusher using Induction (again) with Camera

• None!

•  video  - Series LCR Circuit, Resonance
  (I want all voltages scaled so I can show V_source = V_R + V_C + V_L. Display Colors: Red=AC power, Blue=Resistance(current), Green=Capacitor, Yellow=Inductor. Last year's description says "Use 100 ohm resistor instead of light bulb. Use shorts across L and C to show phase effects incrementally. Hide labels to scope channels and set scale to 2V. Set FG to 2000Hz, 6V." I'd like to inspect it when you have finished setting this up on Sunday. )

•  video  - Electromagnetic Radiation
•  video  - Polarization of Light
  (One polarizer on the projector, another polarizer held by a pincer above the projector about half a foot above. ( Third polarizer will be held by hand to insert in between.) )

• scattering from water with high-powered pen-light and a polarizer demo (that I made up)

•  video  - Ray Optics Kit
• Concave Mirror
  (I want candle light instead of lightbulb shown in the picture. And I want the candle movable from a range of about 3x(focal length) to just next the lens. Can a camera capture all this range? Since I don't remember how it went last year, we need to discuss. )
•  video  - Light The Match
  (On camera )
•  video  - Polarization of Light
  (No need to set up the polarizers with a stand this time, but other than that, usual items please. )

• Total Internal Reflection
  (on camera )
• Light Pipe and Fiber Optics
• Rainbow II

• •Is it possible to put a candle behind the big convex lens and aim a camera at them, just like we did with a candle and concave mirror? The point is that I can move the candle and camera captures how the image size changes.

•  video  - Ray Optics Kit
• The Eye Model I

• telescope made by two convex lenses and a stick, aiming at the back of the auditorium with the image captured by camera (I think we did it last year.)

  red pen laser, green pen laser, vertical incandescent lamp
