Doing the microwave trick to get its wavelength and determine 'C' is an old trick. I did it ~20 years ago with icing, there's nothing new here and nothing to "call foul" about. If you want to claim you were "first", get a time machine.

Cool experiment, but I have questions/concerns. You're assuming (I think) that the wave passes over the peeps without any interference. From my limited understanding of how a microwave oven works I thought that microwaves get deflected by a fan that randomizes the path of radiation. Also, won't microwaves deflect off the interior walls of the oven and "bounce around" randomly until they are absorbed by a polar molecule? The experiment is interesting in it's idea, I'm just a little skeptical and wonder if the results might be coincidental. Guess I'll need to try this with my microwave and see what I get.
@skunkbear
@skunkbear 7 жыл бұрын
You're absolutely right - the microwaves bounce around - reflecting off the walls and interfering with each other. Thanks to the constant position of the microwave oven walls, that interference that produces what is called a "standing wave" - unlike the microwaves produced by the emitter, it's peaks and valleys are stationary. This standing wave's wavelength mimics the wavelength of the original microwave. You can read more here: www.emu.dk/sites/default/files/physics_of_microwave_oven.pdf We deemed wave addition and subtraction too in depth for this overview video.

If the frequency is lower, the wavelength is slightly longer - yielding the same speed of light.

@GFlCh
@GFlCh 8 жыл бұрын
+burmesebeef - He got into his time machine to visit the late 20th century and picked up a laser on eBay... Actually, previous light-speed experiments (such as Isaac Beeckman in 1629), used the flash from detonating gunpowder as the light source. For the Fizeau light speed experiment in 1849, references I have found only indicate he used a "high intensity light source" (not very helpful to your question). But in 1849, they did know about, and have more than a basic understanding of electricity. So (in 1849) Fizeau probably used an electric spark-gap to generate the light. The only thing that (sort of) points to this, is it's mentioned that the equipment which was designed and used for the experiment was adapted from similar equipment he used in previous experiments to determine the speed of electricity through wire.

Why dont we feel these changes in speed?

You treat microwave radiation as a standing wave. How did you account for the microwaves (supposedly) bouncing around the microwave before they hit the target? Or, perhaps the "bouncing" is only the marketing ploy...
@skunkbear
@skunkbear 9 жыл бұрын
Chris S. Good question - it's exactly because a they are bouncing around that a standing wave forms. When two waves of equal amplitude and frequency meet going opposite directions, they add (or subtract) to form a standing wave. If you go to wikimedia commons and search "harmonic standing wave" there's a great GIF that shows it better than I could explain. In a microwave oven this happens every time a microwave is reflected off a wall. The wave and it's reflection have the same amplitude and frequency but different directions, so they form a standing wave. Unfortunately this impedes uniform heating, which is why most microwaves have those rotating trays.

Although there is a big misconception from this video. you coudn't find the speed of light in the micro wave because the engineers that measured the frequency to find out the Mhz were using calculations already based on the speed of light, there for you could find the speed of light with a micro wave only because they already discoverd it and used it to write down the Mhz. :)
