You might already sleep with that the speed of light is 299,792,458 meters per arcsecond , but now you may confirm that number by playing kitchen scientist and melt chocolate . And then eating the results .
The folks at Wired think that this physical science experiment is ideal for all the leftoverValentine ’s Daycandy , but I intend it ’s not bad all year round .
This is what you ’ll be doing :
verify the candy is in a microwave - trial impression box seat . Better yet , take the chocolate out and put in a microwave secure dish .
withdraw the turntable in your oven . ( You want the candy to delay still while you heat it . ) Put an upside - down plate over the turn - thingy , and place your looker of candy on top .
Heat on eminent about 20 seconds .
Take the chocolate out and look for hot topographic point . calculate on the candy you apply , you may have to finger the confect to see where it has cushion . With the cherry cordials we used , we see several shiny spot and one place where the chocolate shell mellow through , unfreeze the sweet syrup at bottom .
Measure the distance between two side by side topographic point . This should be the distance between the peak and the vale ( crest and public treasury ) of the wave . Since the wavelength is the distance between two crown , multiply by 2 . in the end , multiply that outcome by the frequence expressed in hertz or 2,450,000,000 ( 2.45 X 109 )
Ta da . In this example , the final identification number was a bit lower than the factual f number of light , but it ’s still passably darn near reckon the difficulty of finding the precise “ hot fleck ” to measure from . And the difficulty of sacrifice hot chocolate to scientific discipline . [ Wired ]
