miXscope - Snapshot of the Week
Why doesn't the filament in an incandescent light bulb burn up?
The microscope was handheld and the small 4 watt
incandescent light bulb was turned on and then off.
The microscope's auto exposure was turned off
and an image overlay is in the bottom right corner.
A small hole was put into the base of the light bulb.
The movie was captured with a Smithsonian
Computer Microscope at 10X magnification.
Use the left and right movie controller arrows to
step through the movie one frame at a time.
