Superbe démonstration !!!
Just use this formula to get the parabolic points on a sheet of graph paper with an x-y axis:
y = a(x^2)
(x^2 means x squared)
Gran vídeo, excelente explicación.
Very nice demonstration.
Ciao!
rinnovo il mio sincero grazie .. per il tuo video.

Super demonstration 👍
Nice job
Very impressive
Fantastic!!!
hello!
Congratulation! Thanks! Lajos
Cool way of construction a paparbol! THANKS a lot!
Thanks. Also have a look at similar concept done differently

Спасибо братан ценное видео
Neat. (What's the music, by the way?)
verry good
Nice
Grazie, Fausto (Italia)
Amazing 👏

If you have a parabolic dish but in the middle you have a hole and on the Focal point you have a straight mirror would it be directed to a point with the hole?
Can u please elaborate more. Also have a look at this version as well.

Thank you sir
Welcome
Hello, I would love to build this, what material did you use as a flexible mirror
It's acrylic mirror strip. 1.5 mm thick. This is next version of the same activity. ua-cam.com/video/hZNTmxE5zd8/v-deo.html
@@RavindraGodbole thank you very much this means the world
You can also use an aluminium sheet.
Is easier to build a circumference. The focus is on the line at the middle point between the center and the surface of the mirror...
awesome music lol
So, every beam of light that enters parallel to the axis will focus on the same point? interesting! this is why this particular format is the most suitable for telescopic mirrors. I have another question: I believe that the parabola of a mirror, regardless of its diameter, will always have a predefined shape or a universal predefined angle. And I realized that there are mirrors with the same diameter and different focal lengths, some with a greater distance and others with a smaller distance. So, I suppose these mirrors with smaller focal lengths are not parabolic, they are spherical or maybe it's somewhere between parabolic and spherical. considering that the parabolic mirror has a wider angle and the light beams will have a greater distance to meet at a common point. Is this correct?
Diameter of mirror and focal length are unrelated in this case. U can have same focal length with different diameters. Hope it explains
@@RavindraGodbole Excuse my ignorance, but if a parabola always has the same curvature, how can I have different focal lengths with a mirror of the same diameter? I suppose that the same curvature for the same diameter would make the beams meet in the same place. Or does the parabola not have a universal curvature like the sphere?
Bruh, song name. Google is giving me wrong responses.
What can we use if acrylic mirror is not available
You can make a slit/groove in the current path. Try inserting small pieces of glass mirror. You might get identical result. You can also try with good metal strip which reflects light. This you can bend just like acrylic mirror.
Let me know how it goes.
Is it possible to make mirascop by using this?
Not possible. This is for ray path visualization only
Thanks for your quick reply.
what music is this
black
I remember reading "to kill a mockingbird" in freshmen year to this music in highschool
Ok... then logically you can easily develop a reflective surface that can be modified to focus towards the center point and gradually spread out so the whole underside of a pot or pan can get some degree of focused solar energy..It would make a for better cooking application.. or canning, instead of the intense focal point that most parabolas are famous for
yes
