- Let's explore how telescopes work intuitively using a demo. Then we will talk about some nuances involved in ray diagram and derive an expression for magnifying power.

Man this is so much better than that Unacademy . They always brag about killer visualisation but those are just some animations one Google search away. This is original intended to help us.
Yeah totally ayankoeji their videos are totally on spot i feel bad for them for getting very less recognition
khan academy literally showed us in real life
Wow, this man has some serious teaching skills. I wish I had discovered him earlier.
Same
Me too man
Yaar .....now I can feel the beauty of the concept...
The sheer hardwork and enthusiasm!!!! Hats off
This such a great way to explain. Thank you for your commitment to teach others.
sir.....THE BEST EXPLANATION!!!!!!!!
OMG
Awesome
Best explanation 😍
🛐I have seen no teacher like you before, I have learned from many in yt, but I can say proudly you are the best.
Great explanation! I find it's important to watch many videos on a topic.. Each one covers a different aspect of a subject and provides more info overall.. this one was perfect in that he showed howthe purpose of the main objective lens is to create an image within the focal length of the eyepiece and that acts as the magnifying lens... Excellent!
After watching dozens of videos, this one explains and I understand, thank you very much!
More power to ur elbow sir
The explanations are lucid and vivid 🙌🙌
Ngl you are the best teacher everrrrrrr!!! 🛐🤍
Your explanation was really great and the tone of your explanation makes everyone more eager to see the full video. You are wonderful and energetic!

I just loved your way of explaining....
Very useful video .... nicely explained.
Wow u are Amazing!! ❤️💕
Sir, You're just amazing..
I also read few answers written by you on QUORA ( about angular wave number, entropy, fan rotation etc..)
And you're truly AWESOME...
Thanks a lot buddy means a lot :)
This was soo beautiful! I finally understood how telescopes work! Thank you soo much Mahesh sir!
Thank you very very very much for your great and easy explanation ☺️
Amazing , simply amazing
sir im thanking you from my bottom of the heart!!!
man you the goat fr fr no cap 🔥🔥
Learning is just so exciting with you!! #Great_Teacher_Mahesh
Simply Great🙏
Love your efforts.. 👍🏻 n sound💗
God could not teach physics , so he sent you 🔥🔥
Wonderful explanation bro
thank you !
really easy to understand
Amazing!
Your presentation, explanation is very good.
Great video sir
Best explanation ever
Hat's off to you 👍👍
Excellent!
That was too good
the real *killer visualization*
Thats great! What technology aids are you using to draw.. it is very good! Thank you!
thank you so much!!!!!
Thanks so much 💖
This man is is great. Can anyone please let me know the name of this man if it is known ? It would help me to learn better by googling and searching the lessens to learn taught by him.
MAHESH SHENOY😊
Wow fantastic
Excellent explanation sir
Nice work
Nice work bro.
Fantastic 👌👌👌
Yes moon's spots have inverted
I want to become genius like you
why d image does not get blurred by using d objective as d object is not within its focus as explained in d very beginning of the video or we r magnifying a blurred image.
2:06 that's such a lovely drawing of a moon.
Wonderful teaching, please tell me where is the f point in an eyepiece. Is at it's bottom or in the middle.
😊👍
My friend, I am trying to construct a terrestrian telescope, so I need a little help from you, is it possible ?
Thank sir I want to make a telescope like galielio
👍
Sir please please post make a complete course
Please draw a third line showing the bottom of the moon and show how forms through the lens - thanks
Sir one doubt, you said the things near the focal length of the magnifying glass (convex lens) can be viewed without any blur. But at last when you use the convex lens to view the moon at starting , how is that you don't get a blurred image there?
I also thinking it
Its better if u had used a concave lens at the end
It was almost perfect! Everything was good until 5:20 when the eyeball is placed touching the eye piece. Instead of tracing the diverging refracted rays coming from the eye piece and into the eye ball leading us to a magnified inverted virtual image we got something else. At the end you are no longer using the rays you started with as the ones captured by the eye. In your drawing the rays you started with hit the bottom of the eye and do not get into the eye. We thus would not see those rays. Could you please correct it? That way I could share this great video!
Could you please clarify that please?
The blue line isn’t the bottom part of the moon - but you said that it was
Who knows what device is used to make this kind of video?
Vim pelo Astronomia Olímpica
I am I class 8 but understood it, lol😅😂😂
Much much better explanation than Byju guys..
He's the same guy from Byju's...their star teacher, Anand Srinivas
@@lijojosef no he is Mahesh shenoy
Chapter name ?
Ray optics and optical instrument
I love that fake American Accent......lolz
Lmao my teacher made it so complicated, Indians on youtube are better than physic teacher
where are you from?
pharallel 🤣🤣
Plz be desi . don't need to talk like foreigners. It irritates. We need only explanation not ur accent of spoken english.
