Chocolate bar in Microwave (Part-II)

This diagram of the electromagnetic spectrum finds it place in all physics textbooks:

But the problem was I never got a physical sense of what that meant. It remained ‘yet another physics diagram’ for a really long time.

You see, unlike sound which can be neatly visualized using Schlieren imagery

or by other unconventional innovative means,

I had no idea how to even get started with electromagnetic waves.

Visualizing the microwave wavelength using a chocolate and an oven (although not my original idea) arose out of this need to understand microwaves a little better.  (Check out part-I of this post)*

But you can do more with some better but less delicious equipment.

You can get a couple of neon bulbs from an electronics shop and place them in a grid inside the microwave to view the standing wave while the microwave is in action

                                                    Source

This tells you how the heat is distributed at the bottom of the microwave oven. The lit bulbs are anti-nodes and unlit ones are the nodes .

You can also try (NOT recommended) to do this by placing a light bulb inside a cup of water instead of a neon bulbs.

                                  Better quality gif  - here              

As you can clearly see the bulb only lights up in the anti-node regions of the standing wave while the remaining regions are the nodes.

You can take this a step further if you have an infrared camera .

Mark Rober had this brilliant idea of using the infrared camera inside a microwave in order to ensure that food that is being microwaved is cooked evenly and completely on the inside.

And ElectroBOOM then took this to the next level by placing a cardboard box inside a microwave oven and looking at the heat map using a infrared camera.

That last gif my dear friends was the most satisfying physics animation that I had ever seen for a really long time ! It clearly illustrates the 3D standing wave heat map that is produced inside a microwave oven.

Although these aren’t the only ways to visualize the standing microwave pattern inside a microwave oven, but these are the ones that I was able to test them out with equipment that you can probably find at home or at school/university.

You are welcome to suggest more thought experiments, alternate methods or edits to this post, I would highly appreciate it!

Have a good one!

do you ever tire of how, like, dramatic anxiety is?? it’s like. bitch. bitch. it’s not that serious. we’ll live. it’ll probably be a pain in the ass, but we’ll live. so stop making me feel like i’m actively dying.

If somebody likes me, I want them to like the real me, not what they think I am. And I don’t want them to carry it around inside. I want them to show me, so I can feel it, too. I want them to be able to do whatever they want around me.

I miss you. But you’re still gone. You’re still gone.

If your nude photos are posted online without your permission, Microsoft and Google want to know.

For years, most victims of revenge porn — people who have had their nude photos shared online without permission — basically couldn’t do anything about it.

According to one study, over 50% of all adults engage in sexting, and 70% admit to having received a nude photo online or over the phone.

And yet, despite the fact that we all (or at least more than half of us) do it, there’s still this weird, persistent, harmful notion that if your naked pictures get leaked or shared maliciously by an ex online, it’s your fault for taking them in the first place.

It’s completely backward, but sadly, the law seems to at least kind of agree.

As of September 2014, New Republic found, putting someone else’s illicit photos online without their consent was illegal in just 16 states, though laws have been proposed in more states. Not only is it typically impossible to prosecute the perpetrator, they note, it’s impossible to legally compel websites to take the images taken down most of the time.

But thankfully, Microsoft and Google — which operate two of the biggest search engines on the web — don’t think it’s your fault. And they’re finally saying “Enough is enough.”

why are non-millennials so personally offended by everything? like if i’m still wearing my jacket indoors, it’s because i’m cold, not because i disrespect your home/your classroom !! if somebody has got your order wrong, it’s because they’re very busy and simply made a mistake, not because they’re trying to jeopardise your meal !! if somebodies phone rings during a meeting/lecture, it’s because they accidentally forgot to put it on silent, not because they want to disrupt your speech !! just calm down, sharon, not everything is about you

Sometimes I wish we could have grown together.... But either way I'm glad we were able to grow even if it was apart. I'm growing into a flower and you've grown into this beautiful tree, you needed your space and room to grow

Your handwriting. The way you walk. Which china pattern you choose. It’s all giving you away. Everything you do shows your hand. Everything is a self portrait. Everything is a diary.

What makes me sad is that you knew how much I loved you yet you still didn’t stay. See the pain isn’t that you didn’t stay, the pain is the feeling of being worthless in the eyes, of the one who, is all I know.

‘Am I crazy?’ she asked. ‘I feel like I am sometimes.’ 'Maybe,’ he said, rubbing her forehead. 'But don’t worry about it. You need to be a little bit crazy. Crazy is the price you pay for having an imagination. It’s your superpower. Tapping into the dream. It’s a good thing, not a bad thing.’
