MICROWAVE OVEN
- Interior
- Electronic vaccum tube
- Produces short radio waves
- Microwaves travel through a wave guide
- After wave guide they go to a fan-like device that scatters the waves
- Fan like device is called, stirrer
- Waves bounce from wall to wall
- Eventually they enter the food
- Eventually they enter the food
- Fan like device is called, stirrer
- After wave guide they go to a fan-like device that scatters the waves
- Called microwaves
- Microwaves travel through a wave guide
- Called magnetron
- Produces short radio waves
- Electronic vaccum tube
- Molecular Structure
- All foods contain a water molecule
- Act as tiny magnets
- The molecules are pulled back and forth by the magnetic field created by the microwaves
- This back and forth motion occurs two and a half billion times a second
- The rapid vibration causes friction between water molecules
- The friction creates heat
- The friction creates heat
- The rapid vibration causes friction between water molecules
- This back and forth motion occurs two and a half billion times a second
- Water molecules are dipolar
- Dipolar means they have a positive charge on one end and a negative charge on the opposite end
- Dipolar means they have a positive charge on one end and a negative charge on the opposite end
- Rotating microwaves create a magnetic field
- Act as tiny magnets
- All foods contain a water molecule
