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

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?

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??
@fatmaaljufry46564 жыл бұрын
Parabolic
@JustFor-dq5wc2 ай бұрын
So.. for telescope where is that sweet spot where parabolic are much better - 6'', 8''?

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.

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

Is aplanatic points are possible in parabolic mirrors
@TheRushtime2 жыл бұрын
So you can combine 2 types of mirrors - parabolic at the center and spherical at the sides. What is the Formula of parabola?

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.

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