Put anything relatively large in the microwave and cut it in half after heating it. You will see that its colder on the inside. That statement really killed the video for me...

There are some exceptions. For example a jam filled doughnut. In fact, because of the lack of H2O in the dried out bread and the abundance of H2O in the jam center, all the microwave energy goes towards heating the jam. It is in fact quite dangerously deceptive, as you'd take out the jam doughnut and it will feel a little warm, but as you bite into it you'll get a nasty surprise because the center will be extremely hot. Also, as cardboard and plastic do not contain any H2O there is no effect of heating resonance from their molecular structures. This is easily demonstrated by heating pizza in a microwave while still in its cardboard box takeaway container. The cardboard is not hot, yet the pizza is.

Amazing! So, i could learn that a standing wave is concerned by 2 microwaves interfering on each other. A first microwave (incident) is created from an electric source and flows through the resonance cavity. When it finds a reflector, the first microwave reflects and creates a secondary microwave in opposite way. The phase of the secondary microwave is 180 degrees distant from the first one. Implies that at this moment one phase is canceling the other when the amplitude is maximum and minimum, one to the top and other to the bottom. But as the 2 waves is travelling, the distance between the phases isn't static, so when the 2 microwaves encounter at the moment of maximum amplitude for both of them, they interfere constructively, point of maximum energy. That's the reason that the standing microwave formed is applying more energy always at same points, cause the distance between phases is varying, but as it's originated of the same source, they have the same frequency, velocity and amplitude, the points of maximum amplitude of both of them will always be the same. Interesting that the encounter of no amplitude of them, don't create more energy at all. But as microwaves flows, that's the point that they encounter constructively. It was not common sense to me. Thanks!

What bothers me is that the cheese shows multiple hotspots. This is contrary to the picture of a single standing wave. If there is a single standing wave in the cooking (resonance) chamber, then we must have 2 or 3 or 4 hotspots aligned in a row spaced at equal distances. Right? But this is not shown in the "sea of cheese" plate..... I am confused.

@@Mateus-gt2iq: Thank you, but I have to disagree. If you look closely then the experimenter places a square-shaped tray into the oven. It's impossible for it to rotate within the oven chamber given its size. I hope you agree on this. However, your answer could also be interpreted for the case where there is a fan rotating in the ceiling of the MW oven (randomly?) distributing / reflecting microwaves within the oven while the food is stationary. But also this can be argued against because if you look closely the model has the design where food is rotating (rotating mechanism at the bottom). So, if I am correct in my chain of arguments, then the food (cheese) is stationary, the generated microwaves must also be stationary (no reflecting fan in the ceiling). Hence my original question is still open..... Looking forward to your reply. :)

@@Mateus-gt2iq: Thank you for a constructive discussion. What I do not understand is that the hotspots melted into the sea of cheese are not arranged as expected: if there is a single standing wave with travel direction along the left-right axis of the oven, then I would expect 3 or 4 hotspots at equally spaced distances around the depth where the waveguide is located (at the upper right side). But this does not seem to be the case. Its kind of a pity from a didactics and educational point of view: In the 5 - 10 minutes before operating the microoven you imprinted a picture of a standing wave in the head of students, but then the hotspots are not where they are expected according to the standing wave picture...... I hope you understand my point.

Since metal basically reflects the waves back, the inside of a microwave is built out of metal which doesn't let the waves pass through (as they reflect back in), same with the glass that most probably contains a thin layer of metal which does the same job. And so the waves never go outside of the microwave oven but remain inside throughout the duration. That is the reason why, when opening the door to the microwave oven while it is working shuts it off, it's a safety feature as to not allow the waves to go out of the microwave since the door isn't there to reflect it back anymore

This is brilliantly presented explanation of the physics involved in cooking food.
@andrewh23413 жыл бұрын
There were way too many inaccuracies in this video. The most glaring one was cooking from the inside out. While it is true microwaves penetrate food, they are attenuated fairly rapidly and so do not make it to the very center of a mass of food item with any appreciable volume. Microwave ovens still rely on conduction to transfer heat from more outer regions of the food to more interior regions. That’s why the defrost program typically cycles the magnetron on and off. (Inverter based microwaves excepted which turn the power down thus allowing time to conduct heat to the interior in a similar fashion)
@thepredator47113 жыл бұрын
But how bro, I have read in books microwaves have larger wavelength than red light, infrared. Then it will easily penetrate into most food items.So heating should start in the reverse way u mentioned. I am just saying my opinion (school student). Any reply is heartily welcomed.🙂

And, of course, if you're teaching the kids about electromagnetic waves you can use a large slab of chocolate as shown to get the hotspots (disable the turntable first). Then measure their spacing and with a bit of detective work on the frequency and very simple maths they can calculate both the wavelength and the speed of light. If successful, they get to eat the experiment. Might have to do it more than once to get a spread of clear results to average (!)
@TobyOnTube Жыл бұрын
Thank you for raising this issue!! What I do not understand is that the "sea of cheese" apparently shows some random field of hotspots suggesting multiple standing waves. This is contrary to what the video tried to convey: a single standing wave. If there is a single standing wave, then there should be a regular-spaced pattern of hotspots in the sea of cheese. Hope you have a good explanation. Because from looking at the sea of cheese, I cannot make out which distance to measure.

6:25 - Finally someone explained in detail how exactly a food microwave works. So the greatest peaks of the microwave’s amplitude is the one that creates hotspots? It would make sense since all peaks in a wave has the most energy. What would happen if the peak of the microwave is below the food? As if the peak of the wave is actually greatest at the surface of the microwave oven’s floor and not on the surface of the food? Maybe the microwave oven is designed such that the peaks of the wave will always remain at the level of the surface of the food…

each molecule has its own optimal wavelength (or frequency) but only molecules presenting a dipole can 'absorb' microwave. 2.45 gHz is not exactly the optimal for water but it is the closest authorized frequency. Other fluids such as ethanol (alcool) absorb more efficiently microwaves than water to convert it into heat. On the opposite, kerosene (a mixture of apolar molecules) is transparent to microwaves. It is to be noted that the absorption efficiency also depends on temperature.
