I’m In A Long Distance Relationship With The Stars

u r. Planet! !!!!!!

i m… Dwarf! !!!!!!!

you: aww did you just get a cute text from your boyfriend?

me, holding back tears as I smile down at my phone: no, nasa just found 3 earth-sized potentially habitable exoplanets around a single star.

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!

** Why is wavelength of light important than its frequency ?                                                                            

And we think time zones can be confusing!

why do you waste your time like this

because i literally have no life 

ha ha get it because i’m a planet with no life on it ha ha ha 

being uninhabitable is kinda lonely tho tbh someone move me closer to the sun pls

this account has been active for like 3 class periods

honestly what am i even doing anymore  

plox follow

thx in advance

A Message from Pluto

Yeah, I have some bad blood with the other planets. I’ve been trying to hit Neptune for years(he’s a real jerk). I’m just hoping something doesn’t crash into me first(#Can’tCleartheNeighborhood)
