me too🤣🤣
Present 😂😂😂😂😂😂
32:07 second side is polished and first side is reflecting surface
43:24 inward
55:54 convex lenses
56:41 sunlight is of VIBGYOR COLOR because we can SPLIT it into seven color by a prism
1:00:47 by placing a prism in the path of sunlight we can see that sunlight is a composition of 7 colors VIBGYOR
Bro after searching in Google be like
@@Goatnaldo-od6cc chalo usne google to kia😂
BRO..after searching from google...😁😂
Sir Kon Sa lens lagta h Bata dijiye ye please
55:45 the property of human eye lens is convex lens.
32:06 1st is smooth shiny surface and 2nd is polished
43:27 inward
56:00 I think its concave lens
Sir you are one of my favourite teacher of science 🎉🎉😊😊😊😊❤❤ how many students are like alok sir please like 😊😊😊
same here ❤❤
Same here
1. Plane Surface
2. Polished Surface
🥺Miss you bhaiya :( thank you so muchhhhh bhaiya!!✨🙂 For giving all the knowledge and giving fun to that subject which was boring to us..!!
aere yae bhaiya nahi uncle hae
🤫☺
@@deepaktiwari7958 agar aapne intro dekhi ho to Inka sabse best part

Y'all you are right
you can just say teacher❗isn't that hard
From class 9th ...cing it to clear my concepts.....which remained uncleared due to n number of problems
Thanks my dear sir for teaching
The legends are watching it one day before exam but legends ultra pro Max are watching it on exam day like me
Do not fear when alok sir is here
55:31 Ans: Convex lens 👍
56:30 Ans: Multi-coloured

43:24 Ans: Inward
1:0:55 Ans: Glass prism
All answers here 🌟
2nd is wrong it's answer is 'white'

Ye bande bi like : jaldi edit karo re baba
Thank u so much sir, i topped the class in my UT-4 exam
WHICH SCHOOL BRO
Good teaching my dear sir❤❤❤❤❤❤😮😮😮
55:48 answer is convex lens😎
Alok sir you are the best teacher in physics 🙂🤗
To find that sunlight is mixture of seven colours we can use Newton's disc it contains seven colours of rainbow and when we rotate it very fast then we can clearly see the white colour and then we can say that sunlight is mixture of seven colours of rainbow
I am very thankful to you sir ,really I'm saying that I am very confused in this chapter but after seeing our video I'm confident that I will score full marks in my tomorrow's UT. Thank you so much sir ☺
32:07 1st one is smooth and shiny surface and 2nd is polished surface
43:24 Inward
55:42 The human eye has a convex lens
56:40 The sunlight is multicolored. For eg -if we see the a beam of light from a prism , we will be able to see a VIBGYOR
01:04:06 If we place a prism in sunlight we will be able to see a VIBGYOR
(1) smooth and shiny surface
(2) Polished surface
(3) inward
(4) Convex lens
(5) Glass prism
Sunlight is white but when it passes through raindrop 💧 it get converted into seven colour of rain bow because white colour is mixture of all colours
😮🎉🎉🎉❤❤❤😊
Light=A electromagnetic wave which produces the sensations of vision ....❤
Here "e" is bubble so and will be used
Thanks for likes..
no, its a shiny surface or a form of energy and.......in the absence of light we cannot see anything..........
Hi ! Sir my name is Samruddhi
1) Smooth surface
2) Polished surface
3) Human eye is convex lens
I think it is concave lense.
@@funnymovement1583 you are so cute 🥺🥰🥰😍❤️♥️💘
this hits different at 0.25 speed😂😂
Sir becomes nashedi
Really😂😂
A human eye have a concave lens😊
That depends
The lens present in our eye 👀 is convex lens made up of a transparent jelly like material.
Thank u so much sir because of u i could understand this chapter .
Prism
1) Smooth surface
2) Polished surface
3) Human eye is convex lens
Reflecting surface of concave mirror is inward
27:50 ko boy ne left hand upar Kiya aur mirror me bhi left hand upar Kiya 😅
Sunlight -white because white light produces the mixture of different colours
Example -rainbow
Yes right
Aaloo
Wait
Thank you sooo soo soo much...... appka wajah sa Aaj mana 85% score kia..... without any tution thank you so so much 😊🎉

2=Polished surface.
Thanks sir for teaching us you are very intelligent❤❤❤😊

A biconvex lens is the type of lens found in the human eye, and it is responsible for forming genuine images. It works by focusing light rays onto the retina. The eye lens is made up of peculiar elongated cells that have no blood supply and rely on the aqueous humor for nutrition.
