Remove the ring on which the turntable rotates from the mic, so that it cannot rotate. Then, put a chocolate bar on the plate and bake it on full power for 90 seconds. When you take it out, you will see a couple of holes in the chocolate that will allow you to measure the speed of light.
The explanation. Microwaves, being confined, form stationary electromagnetic waves. These are responsible for the pair of dimples. Measure the distance between them -in our case, 6 cm- and multiply it by 2 and by 2,450,000 -the frequency of the microwaves-. Result: 294,000,000, a figure that expressed in m / s is close to the value of the speed of light that is obtained in physics laboratories (299,792,458 m / s).
