- Convex and Concave Lenses are Spherical Lenses. We look at the Image Formation by these spherical lenses using ray diagrams. Light ray rules for Convex Lens and Concave Lens are discussed. Using these rules we can find the position and properties of the image. I'll be the object in this video and you need to find my image!

Am watching it cuz I have exam tomorrow 😢
Same
bruh
He explained them very clearly and understandable in just 18 minutes thought I'm gonna spend an hour or hours researching this
The reason that I'm liking physics is your explanation.
Thanks. Glad to hear that

here i am in 2024 and its night before exams...who is in a situation like me?
me😅
Tumhari bhan ko naman❤❤
1) concave lens.
2) convex lens, Between F1 and o ( optical center of the lens).
3) convex lens, position of the object should be at 2F1 and position of the image is at 2F2.
I'm soo happy that some people actually take their time to make things like this to help students abroad. Thank you very much.
Ok cancel
Q1. Concave lens
Q2. Convex lens is used and the object should be places between optical center and F1
Q3. Convex lens and position of object is at 2F1 and position of image is at 2F2
wow i agree with you
Whose board is in 2023-2024 attendance here ??😂😊

thanks for the info, i learn a lot
Legends watching it just a day before exam. Just like me !
good u are saying urself a legend
Here's what I comment:
Q¹. Name the lens that always forms a virtual, upright and diminished image.
Ans: It is concave lens that always forms a virtual, upright and diminished image.
Q². Which lens is used in a magnifying glass and where should the object be placed?
Ans: It is convex lens which is used in a magnifying glass & the object should be placed in between the focus and the optical center of the convex lens.
Q³. An object of height 5 cm is kept in front of a lens. An inverted image of height 5 cm is formed. Identify the lens & position of the object & image.
Ans: It is convex lens. The position of the object & image is 2F (2 times the focus, F).
Sir, your video is really highly informative and practical. Thank you so much, Sir. Commented with ❤️ from Dharmendra from Nepal. Hare Krishna🌹🌹🙏🙏

Finally we are found the best teacher in 2020 thanks 😍😍 sir for this amazing explaination
It's my pleasure
Well explenation sir
Not 2020 its 2021
No but also in 2021
🎉🎉🎉
I really appreciate your style of imparting knowledge. Here are the answers of questions.
1. Concave lens
2. Convex lens and the object should be placed f1 and optical center
3. Convex lens
Position of object = 2f1
Position of image = 2g2
Excellent!! All your answers are correct :) Also try the Quiz for this video on my Website. Quiz button is below the video: www.manochaacademy.com/physics/light/l/convex-and-concave-lenses
Pls explain ans 3
Why for the Q2, object placed at f1? since it will build image at infinity...

This man made me understand it for real like its 3 am
Honestly sir, I have never seen such a thorough lecture on this topic explained CLEARLY, CONCISELY, and with perfect imagery. Seriously, bless you for creating this video because for the life of me I couldn't envision optics until your video. You went full on hard with this video with so much effort and I already know you're one of the best teachers I've encountered after just this video. Thank you!

Watching just before my board exam.... very helpful video. .....
The most interesting thing is that sir made explanations with very simple activities !
Awesome
Can we talk about how he is very friendly and nice, away from explaining stuff very good, he replies to all the comments even the ones made yesterday ( he made this video 4 years ago )
Thank you mr. Manocha 💛

Thank you Bhai ❤️❤️
Thank you so much sir
It’s really clear
You are a way better teacher than both my school and tuition teacher
May universe bless you

omg you just saved me for my finals!!! Thank u so much I would’ve never understood the concept without this video
Thanks for this golden content sir!!
Most welcome

Q2 Convex lens
Q3 Lens is convex lens
Object is placed at 2F1
Image is formed at 2F2
beyond f2
you're right I wrote that by mistake
@@pradhyumna.n-312 yaa it's beyond f2
Dear sir, this video was amazing. I really liked the style and the editing was superb. Keep up the good work. You managed to teach me a concept I thought I would never understand! Thank you!
my life saver!! Thanks sir!!
Q no 1 Concave lens
Q no 2 Convex lens and the object is placed between optical centre and focus
Q no 3 The lens is convex lens and the position of the object is at 2F
Correct answer, brother 🙏.
Hello all friends ( I’m a simple student from Cambodia 🇰🇭 in grade10 ) I really like this video I’m supporting it !
Happy to hear that you liked the video! Thanks :)
Manocha Academy ok 👌
Im from philippines and we have the same lesson
Rodj Daniel George Yeah I’m have this lesson too. We come from different country !
@@twincar168 may be in different countries United by the subject.✊
I never ever understood lenses and image formation so clear before this video😢
I am very very thankful to you *SIR* , for such a smooth explaination about image formation, MAY GOD BLESS YOU😌🙂

2 minutes before my test😭
Tomorrow is my exam 💀

You are the best lecturer ever!
are you rinkiya ke papa?
1. concave
2. Convex , object should be placed at distance less than focal length
3. Convex , position of object is at 2F1 & image is 2F2
This is by far one of the most useful videos on this app thank you great lord
Ans1: Concave lens
Ans2: Concave lens The object should be placed in between F1 and lens
Ans3: Convex lens, 2F1 and 2F2 respectively
Doubt 1: How can we see the magnified image from the magnifying glass if it's a virtual image
Doubt 2 : Why is F1 and F2 of the Concave lens is opposite side of the Convex lens, can they be on the same side?
Thank you for your teaching, it makes me understand more about how lens work.😊
❤❤❤❤
Literally Sir ...u are one of the best teacher I have ever seen. U are simply amazing 👍
Thanks a ton
