Measuring the Speed of light, using Chocolate, and a Microwave Oven
Created | Updated Jul 1, 2006
This comes from a booklet called 100 things to do Before you Die that was published by the Publishers of New Scientist.
You will need ;
1. A bar of Chocolate, UNWRAPPED.
2. A Microwave Oven, make sure you know the frequency it operates at.
3. A ruler.
This is what you do;
1 Take the turntable out of your microwave.
2. Place the chocolate inside and heat for about 40 seconds.
3. Measure the distance between the "hotspots" in the chocolate.
4. Multiply this distance by 2 and then multiply that figure,(the wavelength) by the frequency and you should come close to 299792458 metres per second , or the speed of light.
