In this video you see my son Tom and I conducting a simple, yet important experiment, that allows you to approximate the speed of light only using a microwave oven and cheese. How? Well the speed of light is equal to the frequency times the wavelength. And a microwave oven comes with an indication in the back that shows the frequency. Ours is 2450 MHz. So then all you need to do is to melt cheese in a plate and with a simple ruler measure the distances between the first two areas in the cheese that start melting. In order to do this it is important that you prevent the platter of the microwave from turning. For other details just watch the video.
