Incredible Measuring The Speed Of Light In A Microwave References. Web the aim of this experiment is to measure the speed of light using food (chocolate, cheese, pappadums or marshmallows), a microwave oven, a ruler (with millimetre measurements) and the relationship between the speed of emr (in this case microwaves) and their wavelength and frequency. This is a great experiment for kids.

Because microwaves are a type of light you have just measured the approximate speed of light. Web to calculate the wavelength, first multiply your measure distance between marshmallow peaks by two. Microwaves get their name from the part of the electromagnetic spectrum in which they operate.
