Spherical & parabolic mirrors

In this video, we will explore two kinds of curved mirrors, parabolic and spherical mirrors.

Amazing how clearly this was explained -- It takes a very talented individual to do that.

[@baranjan4172]

Since a cooking pot is not a point, it looks like the spherical mirror is perfect for heating the sides of it. Good demonstration. Panel cookers are easy to build this way.

Dear Sir, It's amazing to see that you motivate and clear the doubts of many students through experimental videos based on physics concepts. I also watch your videos regularly. Thank you for your kind words! I appreciate your efforts, and please accept my request as an opportunity to clarify more about antennas. When discussing TV antennas, it's important to note that they are typically parabolic in shape. This design allows them to effectively focus incoming radio waves onto a receiver, resulting in stronger signal reception. Parabolic mirrors indeed concentrate light at a single point, typically at their focus, making them suitable for applications like solar energy collection or telescopes. In contrast, concave mirrors may exhibit less intense focusing, sometimes resulting in the spread of light along the principal axis rather than at a single point. Additionally, when considering one-point focusing, parabolic mirrors generally cover more area than concave mirrors, except in cases where the size of the mirrors is significantly small.

If I am understanding this correctly if you wanted a Spherical reflector that was 4 times as large you could start with a Sphere reflector that is 4 time as large and only use that part of the Sphere?

Thank you, my respected lady, for the valuable information on how to use the sun's rays in the field of cooking

[@naveenmeena6716]

You deserve a like.

[@jdtaramona]

Thanks a lot for this very clear explanation. Greetings from Perú!!!

[@sivava1500]

Just wow. THE BEST

[@giovannig.624]

Excellent video! Thats why there are cheap reflector telescopes, and expensives reflector telescopes.

[@reypolice5231]

Can you tell me how many degrees of the circle reflect to a point like the other? This way I can just make a part of a bigger circle. Thanks.

So which concave mirror headlight of the car is?? Parabolic or spherical??

[@fatmaaljufry4656]

Parabolic

[@JustFor-dq5wc]

So.. for telescope where is that sweet spot where parabolic are much better - 6'', 8''?

[@buzzwerd8093]

Spherical mirrors are good for wide targets, like a solar oven. You also missed the elliptical mirror that focuses sunlight to a point. Many car headlight reflectors are elliptical.

[@tomburgess8485]

I know this is old but as not to mislead people an ellipse is a parabola. Elliptical mirrors are parabolic mirrors

[@behappy-ki3eg]

Is aplanatic points are possible in parabolic mirrors

[@TheRushtime]

So you can combine 2 types of mirrors - parabolic at the center and spherical at the sides. What is the Formula of parabola?

[@bebizambi392]

y²=4ax

[@aliyahya7702]

Thanks

[@itzMizanforU]

bt which one has the widest field of view???

[@JoAkh]

Well done for the explanation 🙏

[@GUNJANKUMARPANKAJ]

Thanks sir ji... 🙏🙏

[@isbocetvargas558]

Hi. Do you know how calculate "AEL" aberración esférica longitudinal?( i dont know how to say it in englih) is a short Line formed by all focus points because of spherical aberration. Please if somebody knows tell me.

[@gamingwithlegends7006]

I don't know

[@kiranbhat4902]

Mahesh sir why do we see an inverted image of our face in a spoon as inverted images are obtained only on a screen????

[@comicbest2662]

How good that was.really amazing but only 9.6k views so far!!!!¡!!!!!!,,

[@Hey_you_______x]

Hey. Nice. Thank you.

[@apsaraknaik9159]

Sir please upload all the chapters,I m preparing for Neet entrance but I lack conpectual knowledge in physics,But through your videos Its fun to learn physics .please sir try to upload ,if not all atleast 80%of chapters please

[@shrinivasmudigoudar6570]

Nice

[@nathraoaade7303]

Can u please mathmatically prove why parabolic mirrors focus at a point?

[@Ahsrab21]

Thanks alot😇

[@sureshmk6958]

My doubt cleared, thanks.

[@jasminesharma4869]

Whats a caustic curve btw

[@Vedicaa]

Thank you.

[@kiranbhat4902]

Mahesh Sir if the parabola gets bigger and bigger will the rays still be perfectly focused?????

[@kevinjones9586]

Yes

[@alfansarifudin6469]

What is the equation for calculating the focus of a parabolic curve?

[@Raj-xt4fk]

Focus of mirror is the focus of parabola

[@mcocterminator1100]

Excellent

[@mfblowfish4671]

For the use of Concentrated solar power, could you just reshape the receiver to still collect the thermal heat effectively on a spherical mirror?

[@lateefahtijani8665]

Thanks a lot

[@harshgupta7752]

Great explaination....loved it❤️

[@staffernlab-redliquidmercu1330]

Parabolic liquid mirror with mercury magnetic field increase power for telescope, added to frequency , called advanced technology

[@g.revanthkumar3553]

Pls keep notes of this chapter.

[@CorruptMem]

Welcum to appl suppot

[@jasuni554]

Why are solar cookers and such so popular in india?

[@Hey_you_______x]

Duh.

[@Hey_you_______x]

Um, duh?

[@Hey_you_______x]

I know....

[@Hey_you_______x]

Um drrrrrrr, i dunno.

[@Hey_you_______x]

Drrrrr Reeeeeeeeeeeeeeee

[@zubaidarahmanradia5232]

I do khan academy at school lol

[@prakh1250]

Is everyone in the comments section a bot..?

[@apsaraknaik9159]

Sir please upload all the chapters

[@jatinyadav9981]

What's with the fake accent?

[@ramzihammoud5762]

Absolutely no one... Parabola

[@nayantechnology]

Thanks

[@bittusingh6269]

Thanks
