Why is it said that a piece of chocolate can measure the speed of light?

I think it's just an experiment on the Internet, and it's not really measurable.

First of all, there is a formula to understand:Speed of the wave = frequency * wavelength. Microwave oven, microwave is a type of electromagnetic wave, the speed is equal to the speed of light, and in the induction cooker.

The frequency will be indicated in ghz, i.e. 1000 000

000hz。And then how do we know the wavelength?

It's time for chocolate to make an appearance! Remove the dial from the microwave oven, so that the chocolate will not be evenly affected by the microwave, after 60 seconds in the microwave oven, take it out, and find that it is partially melted, and part of it is intact, and measure the length of the unmelted part, that is, half a wavelength. The speed of light can be calculated.

This is provided that we assume that the theory of relativity applies equally at the speed of light, or that its mass still adheres to the basic definition of relativity. In fact, the current laws of physics are basically no longer applicable at the speed of light. In the same space, achieving the speed of light, theoretically considered impossible!

But,At the beginning of the universe, at its time, space expanded much faster than the speed of light, but this is the expansion of space. It's not the superluminal speed of an object, but perhaps to achieve superluminal speed, you have to break the limits of space.

The places where food is connected to low temperatures are static nodes where the amplitude of electromagnetic waves is zero. The place where the amplitude has a maximum or minimum amplitude is called the belly of the wave, and the food is heated at the belly of the wave.

I think it's because chocolate can be used as a useful tool to measure the speed of light.

It's just chocolate as a prop, but other things are okay, and it's not just chocolate.

This is just an experimental statement on the Internet, and it is not really measurable.

Not only chocolate, but also other props, and other items are also acceptable.

This feeling is probably not real, it can't be achieved this way.

I think that's a scientific statement, and we don't know exactly how it works.

In fact, this is an online experiment, the purpose of which is to eat chocolate.

This is to prove the speed of eating chocolate, it's just some Internet terms.

Although the speed of light has been measured by scientists, if we want to measure the speed of light in our daily life, we can use electromagnetic waves, for example, microwave ovens are commonly used tools.

Chocolate is heated in the microwave to measure through the wavelength band, which is close to the speed of light, because there is attenuation in it. It's not true that there is exact. It's a good idea.

The speed of light is 300,000 kilometers per second, and if you want to measure the speed of light, you may need to rely on the speed of microwaves, so you can heat the chocolate in a microwave oven and compare the speed.

It is necessary to melt the chocolate in a microwave oven, measure the distance between the two melting points, calculate the wavelength of the light by an optical formula, and use the frequency of the induction cooker to compare the electromagnetic frequency to calculate.

This one...

I don't think there's a way to return chocolate per se, but there are indirect ways to do it, like giving chocolate to an astronomer and asking them to tell you.

In the British magazine "New Scientist", there was a column dedicated to some "science experiments that can be done at home", which used interesting ways to convey scientific knowledge, such as which way to get tomato sauce out of a glass bottle is the easiest way? Shaking the bottle desperately? Or heat the bottle to increase the fluidity of the ketchup?

Or another way, what is the result, let's do a controlled experiment.

Here are a few interesting experiments in How to Turn a Hamster into a Fossil:

How to measure the speed of light with chocolateTo explain in detail, we must first understand a formula: the speed of the wave = frequency * wavelength, so what is related to the speed of light in our home? Microwave oven!

Microwaves are a type of electromagnetic waves, the speed is equal to the speed of light, and its frequency will be marked on the induction cooker, the unit is GHz, that is, 1000 000 000Hz. And then how do we know the wavelength? It's time for chocolate to make an appearance!

After 60 seconds in the microwave, you will find that it is partially melted and partially intact, as shown in the figure above, measure the length of the unmelted part, which is half a wavelength. The speed of light can be calculated.

After watching this experiment, I have to say that the person who came up with the idea is really smart!
