In this experiment, I spread butter on a piece of bread and looked at where it melted to discover the wavelength of that oven. Afterwards, I looked on the the inside of the oven cover to find the output of the oven. Using these measurements i was able to form this equation. 2,450,000,000H * 12cm Which came to 2.940x10^10. Seeing as how the speed of light is around 299,792,458 m/s, my conclusion isn't particularly far off the mark.
