Introduction: You’re Gonna Do What with my Microwave?!? • Test the microwave absorption of various substances • Offer an Explanation • Look at Other Cool Things that Could Be Done Waylon Flinn, Spring 2001
Microwaves: from the Kitchen to the Laboratory • Things that Don’t Work • Metal • Wood • Plastic • Things that Do • Water
_ + _ + So What’s Going On • Electromagnetic Interaction: The Dipole Moment • Electrical Interaction and Rotational Freedom
Medium Further Investigation • Strong Dipoles in the Liquid phase • Water - 1.87 • Methanol - 1.7 • Ethanol - 1.69 • Acetone - 2.88 (Numbers given are dipole moments)
Medium Water Non-absorption: Hey, is this Thing Broken or What? • The Aforementioned: Non-Dipoles, Metals and Complex Structures • Metal • Wood • Plastic • Other Stuff • Ice • Polyurethane
Conclusion: Don’t Try This at Home. • The Key is a Good Apparatus • I wish I had one • Electrical Properties + Rotation/Deformation + ? + … = Absorption • Still some cool things to try
