Convex and concave lenses are two types of optical lenses that are commonly used in various optical devices like cameras, eyeglasses, microscopes, and telescopes to manipulate the way light rays converge or diverge.
A convex lens, also known as a converging lens or a positive lens, is thicker at the center than at the edges. It causes parallel light rays to converge or come together at a single point called the focal point on the side opposite to the source of light. This focal point is also known as the "real" focal point. Convex lenses are used to correct farsightedness (hypermetropia) and can magnify objects. They are commonly used in magnifying glasses, cameras, and telescopes.
A concave lens, also known as a diverging lens or a negative lens, is thinner at the center than at the edges. It causes parallel light rays to spread out, or diverge, as if they are coming from a single point called the virtual focal point. Unlike the real focal point of a convex lens, the focal point of a concave lens is virtual and doesn't actually converge at a point. Concave lenses are used to correct nearsightedness (myopia) and are often used in devices like eyeglasses and certain optical instruments.

Amazing methodology...dear sir❤❤❤
Thanks a ton
Please try to do more experiments like this.. the way of easy to learn
You are the best teacher in this world 🌏
really Loved the explanation!!
As always AMAZING!~

गुरुजी त गजबे समझाए । गजब।
Pehli baar achi tarah seh kuch samajh aaya

Sir you are really a genius teacher . Your explanation is very good, i watch your all videos. Are you give me your notes of class 10 , please give answers
wow😍thankyou sir for this amazing explanation
Thanks sir please make other video for full explanation of what is lenses and it's types
Magnify image converge light rays when used in spectacles the power delivered to the corneal plane weakness as the vertex distance to the eye increase is convex lenses correct or wrong
Thanks for the forecast! Just a quick off-topic question: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?
The explanation was nice
My all doubts are clear by seeing this vedio. Thank you so much Sir 🙏
Very nice explanation sir
Such a nice explanation
Awesome videos sir💯💯
Really impressive dear sir....💚
From Pakistan ❤
HI SIR
YOUR ARE VOICE IS SUPERB
🎉🎉
Thank you so much 🙂
C'est quoi cet appareil noir qui produit des rayons lumineux parallèles ?
thank you sir ❤🎉
Sir you are best teacher
Sir what is the price of this kit
Sir what is the difference between the planeo concave and concave lens or planeo convex or convex lens
Thanks you that excellent explain
Best ever❤❤❤❤
Thank you sir 😊
Excellent explanation
Can u tell why refraction did not take place in rectangular glass block
See, it is very easy. The rectangular glass block is a transparent material and there is no curved or any irregular shape present, so it is not a lens. There is also another transparent block but it is by two curved edges on either side, so we can say that the structure of the block helps in the refraction of light beams. As it is not a lens, it does not refract, the beams pass through and resultant light is reflected to our eyes processed into vision. I hope this clears the doubt
@@thetheatreofentertains8799 tq
Thank you sir ji
Welcome
Thank you
salam sir for your efforts
Many many thanks
Good explaned❤
Excellent sir
such a nice explanation sir !!! it is so clear when u explain any topic of any subject
Sir please explain social subject for 10
Bro literally taught all of year 8 science in 5 mins
Sir What's wrong with my lense it doesn't show like this?
Also give this type of animation for spherical mirrors
Yes please
🎉🎉🎉❤
The kit is 3000😂😂😂
Thanks you sir
Thanks you sir for this experiment ❤❤❤
You're the best
Thank you!
excellent
Wow amazing experiment
I’m so exited I’ve remembered something I learned years ago is so amazing and understandable
Thanks a ton!
sir concavoconvex and convexoconcave also pls
Nice video
thank u sir
thanks bro
M afraid we didn't have TH-cam in out time, else i would be in Services in stead of Defence
❤❤❤❤
Good sir I am your student from 🇵🇰
Allu❤aima
Nice 👍 you
God bless you Sirrrr!!!❤😂🙏🥰
Hello sir, i need a seperate video of explanation of centripetal acceleration and centripetal force. Please upload the video as faster you can sir please. As my exam is on the way to reach its dead line. Before that i need to learn. But i couldn't find a teacher explaining like you sir. Your way of teaching is made easy for me in every chapters sir. So please accept my request sir. Please
U only see ur 1st video of concave and convex mirror
Nice
Sir concave is converging lens sir
Concave mirror is converging mirror , convex mirror is diverging mirror whereas
Concave lens is diverging lens,
Convex lens is converging lens.
Kon kon use paper ek din phele 2x pe dekh Raha hai
I don't understand this what can I do to understand it🤔
Just do concentrate 😂
Sir Hindi me video banaya kariye
Will try to upload more Hindi videos soon!
But ur saying very good anna
Jaat
😮😮😮
🙏🙏🙏🙏🇮🇳🇮🇳🇮🇳
Ur saying concave lense to convex
I think you roung dear
nice bllody hell acdemy
Jaat
Vimal juna kesri😅
Superb
I don't understand stand mad
You mad your whole family mad
Family pe kyon ja rhe ho@@madhusudangour4600
I scored in science 80/77
हिंदी नहीं आता क्या गुरुजी।
Come to the point as video starts
Thanks
Excellent explanation
❤❤❤
