Urm, hi, the invisibility cloak is real and all of my Slytherin dreams have come true
Hello and welcome back to IO, I am your host Rebecca Felgate and today we are talking about
the legit ability to become invisible.
I just told you I am a Slytherin, but do you know what Hogwarts House Charlotte Dobre,
the Potato Queen is in?
Let me know in the comments section down below!
If you know your Hogwarts house, also tell me in the comments and leave a thumbs up for
this video.
Also if you guys wanna connect with me on social media, the link to my insta is in the
description box below.
RIGHT spectral cloak me!
So, visibility and invisibility pretty much comes down to light and refraction, basically…
light tricks.
Scientists have long suspected they could manipulate light in order to disguise something
– like Hazzas cloak does when he wants to walk around Hogwarts after hours.
When you see things, what you are really seeing is the way light interacts with objects.
The thought process behind the cloak is that developers could make 3D objects invisible
from all directions by selectively transferring energy between certain colours of the light
wave – so by changing the way the light interacts with this object.
After the wave has passed through the object, the device used in the spectral cloak would
restore light to its original state, thereby making just the cloak invisible.
With me?
Cool.
Luis Romero Cortes, a member of the Optical Society, said Conventional cloaking solutions
rely on altering the propagation path of the illumination around the object to be concealed….
He continued by saying that their solution is better because it would allow the light
waves to pass through the cloak, rather than bending around it, which wouldn’t create
a full visibility effect, just a distorted effect.
It’s complicated, but this is how it works – for example – if the object reflects
green light, the light in the green range would be shifted to another colour, so there
would be no green light to reflect, making it seem invisible….
Then, when the wave has passed through the object, the invisibility device would reconstruct
the wave, reflecting the original colour.
Yes, it sounds complicated, but it is always worth trying to understand the science behind
things….
If you can’t get your head around it yet..don’t worry….
Invisible cloak, yey!
The team behind the invention tried out their cloak with a lazer pen and it was successful.
As of yet it seems the invention is still in its prototype phase, so we don’t know
when, or if, us muggles will be able to buy one or how much they would cost.
Did I say muggles?
I strongly believe that with science, magic is possible!
So, would you want an invisibility cloak?
What would you do with it?
I’d use mine for sneaking backstage at cool concerts!
Imagine!
Let me know what you are going to do with it.
Okay, before I tell your Charlottes Hogwarts House and we wrap up this video - I am going
to read some comments from a Video I did about a week ago about a Chinese Satellite crashing
into earth.
Oliver HOlgersson said: i've seen a falling star a lot of them in the same night acctually
on one date i think every year i think i don't know what date but on that date there will
fall a lot of them i saw like 8 i Think it's somewhere in August?
– Ooh, that is interesting, I wonder what that is about.
Lucy Murdoch said: I mayyyy have read the title as “Another cheese satellite is going
to crash into earth”?
OH!
No sadness there!
- So… if you wanna know what Hogwarts house charlotte is in, there is a video on my youtube
channel of her and Azzyland doing their entire Hogwarts House sorting quiz…so check it
out !
