This is a graph of the 2.4Ghz to 2.5Ghz spectrum over a period of 20 seconds of microwave usage. The horizontal direction is frequency, the vertical is time, color is power. Blue was around -80db and yellow around -60db. The data was collected using a signalhound BB60C usb3.0 spectrum analyzer. The graphs where created by their default gui program, spike. Admittedly I didn't do much to make the graphs very pretty and I'm sorry if they aren't up to snuff. I just found the results that the frequency would change so much based on positioning of the items inside of it very surprising, and so may be others would too.
The top graph is the baseline and on it you can see some Wi-Fi packets around the 2.3Ghz and 2.45Ghz-2.6Ghz range. Following is the first test I did where I placed a ceramic mug filled with water directly in the center of the turn table so that it didn't shift its xy position inside the microwave very much. The last graph is from when I put the ceramic mug of water on the very edge of the turn table so that it would have the most xy motion inside the microwave. I did each trial three times and they all basically looked the same so I didn't include the additional graphs but I can add them tomorrow if people so desire. If there is demand I may also test other food items, like pizza rolls.
edit1: to address people concerned for my safety because my microwave is leaking:
It isn't, microwaves can't be perfectly insulated and they have a fuck load of power to dampen. Inside the microwave, it's like 1000w of radiated power which is like 60db. Outside the microwave, I only measured at most -60db. That is about 0.000000001W of radiation power. Granted the antenna I used wasn't perfect so the actual ambient power level was higher. But still vastly below any amount of power that could cause harm.

Could you theoretically have an arrangement of objects that, when microwaved, form an image on the spectrograph?
Edit: woke up to a stuffed inbox and gold! Thanks, stranger!

Huh.... I might have just solved my roommates and Is spotty internet during dinner time.
Thanks for that
