Board ke exams ke 2 months pehle ऐसा lg raha hi ki god ne kisi farste ko bheja as physics wallhe sir hmai dhoobi hui naiya ko par krne ke liye.tnx
Bhai Saab Kya Tharif ki hai😂
Shuuudhhh Hindi .....bhai MAZA agya 👏🏻👏🏻
Hn meri nayayi to bich me hi atak gyi Bhai 🥱🥱
Bhai kitna persentage aya tha
Areee! Kitna jhuth bologe😅😅
Rakshak sir you explain everything so clearly that after listening to your lectures all doubts get cleared and even the most difficult topics seem to be crystal clear .Thank you very very much.
✨ *Rules To Obtain Images* ✨
🌺 *Concave Lens* 🌺
1. Parallel to P.A = F²
2. F¹ = Parallel to P.A
3. O = Underiviated
🌈 *Convex Lens* 🌈
1. Parallel to P.A = F¹
2. O = Underiviated
3. F¹ = ⟂ to O

Thanks A Lot Sir👑💜🥀✨

Haha😌
Sir rules of concave or convex lens
Second rule of concave lens is (A ray of light appearing to meet at the principal focus of a concave lens after refraction will emerge parallel to the principal axis. )
Sir I don't comment you but
by mistake you teach wrong of second rule of concave lens...... By the way your explanation is very superior 💜
Yes sir because jis trah aap pdhate ho usse all clear & thanku for teaching us through your classes I solve the numerical of physics

Thanks sir, frankly i ain't (was not) a studious student but this got interesting with you. Thanks again.....🧠👍

a) parallel to principle axis
b) Apear to pass through F1
c) parallel to principle axis (not sure )
Session was rocking waiting for next lecture 🖤🤔
sis but about the third one isn't it a concave lens so ray falling on the focus refracts parallel to aperture
🐨
Sis it is diverging so there's no way to go parallel to principal axis so it can be according to third rule that it will pass perpendicular to principal axis(through aperture)
👍👍👍
Best of luck 🥇👍😀

C ) can u explain how it's parallel?
Sir really i haven't seen a physics teacher like you. Mere school me to physics teacher bohat bura padhate hai. Pahale to mujhe physics kuch samjhata nahi tha na hi interest tha. Par physics wallah ne ye channel launched karane ke baad mujhe physics bohat intresting lag raha hai. Thank you so much sir 🤗
Mere school ke bhi phy ke teacher bhut kharab padhate hh😥😥😥😥😥😪😞😞😞

Sir aapki explaination sabse zyada logical aur sabse zyada best hai❤❤
sir your lectures are seem to be very clear and most fascinating that's why we all love to watch ur lectures . love u sir . LOVE FROM ODISHA ❤

Very much thanks sir mujhe real image ka asli matlab smjh aa gya aaj nhi toh main sirf sochta tha ki image jo TV wale screen pe form hoti hai use hee real image khte hain. Very much thanks sir🙏🙏
Being a teacher I would say that it takes a lot of practice to explain like this Sir Thanku so much for all your videos 😇

Sir your teaching style is fantastic
. Physics is all about imagination according to Albert Einstein and in you lectures this is present.
Sir if distance of radius of curvature is measured b/w O and C than the whole sphere will become smalll. 4:23

1. Parallel to principal axis
2.Towars F1
3.Parallel to aperture
Thanks bro
Correct 💯
Not parallel to aperture bro..... parallel to principal axis🙃
@@hope.. *perpendicular to principal axis actually not parallel since it's the case of concave lens
In convex lens when passed through focus the light rays goes parallel to Principal axis
In concave lens when passed through focus right rays goes perpendicular to principal axis or parallel to aperture
Great teacher
16:34 sir ncert mein di hui hai ki 'A ray of light appearing to meet at the principal focus of a concave lens, after refraction will emerge parallel to the principal axis.' Sir to ye likh sakte hain kya?
Actually book mai 2 nd principal focus ki baat kari hai and yaha sir nai 1 st principal focus sai light nikaldi sir batana bhool gye bas

45:30 || to PA , at f1 , at upward aperture
But sir rule no. 3 to obtain image is different in ncert . It say that A ray of light appearing to meet at the principal focus of a concave lens, after refraction,will emerge parallel to the principal Axis.sir I'm getting confused 17:29 please clear my doubt sir
Every student want these types of teacher
Sir total internal reflection bta dijiye n

Thank sir rakshak you
Mja aa gya feel ho rha hai physics oy e hoye kya padhaya hai
FROM THE DEPTH OF MY SOUL I WOULD LIKE TO CONCLUDE THAT RAKSHAK SIR IS ACTUALLY OP OP OP OP OP!!!!!!!!!
bahut achi tere samjachuki hai bahut shukriya Rakshak sir
Sir 🙏 numerical of all chapter video banaiye.
Sir in challenge ques..
1.) Parallel to principal axis
2.)the ray diverge and meet at F1 with size highly diminished and position virtual and erect...
But I don't know what happened in third plzz tell me the answer 🤔🤔🤔
It will coincide principal axis (because ray passes through F1 will perpendicular to Apperture similarly ray passes through F2 will coincide principal axis.)
Sir please 15 march tak syllabus complete kara do pre boards aa rahe hai
apperture of spherical mirror=(πd^2)/4.......where d is the diameter of the mirror...
1) parallel to principal axis
2) appear to f1
3) parallel to principal axis
Thanku to confirm the answer ❤❤
Sir kyq padhaya hai sir ye bhi aur mirror image formation bhi hats off...
Sir...Light ke lectures itna gap se upload ho rhe hai...ki maza nhi aa rha paddhne me...mtlb paddha to Rakshak sir hi best rhe hai par... Regularity nhi ban paa rhi...😶

Honestly refraction mere sar ke upar se jaa raha tha but sir made it easy. now Its completely clear to me
Sir plz refractive index ke problems kra do jldi mere preboards hai aur mujhe sirf whi pe problem ho rha hai
Challenger Questions
1. Will become parallel after refraction
2. It will diverge in the line of F1
3. It will become parallel to principal axis
Superb Lecture 😙😙😙😙😙
sir i have one doubt
aapne bola ki covex lens me 3rd case me refraction nhi hoti
lekin aapne 3rd lecture me bola tha ki refraction tb nhi hoti jb ray normal pr hoti h ya dono ke refractive index equal hote h
pr 3rd rule me ray normal pr bhi ni h aur glass or air ka refractive index bhi equal nhi h
to fir refraction kyu ni hui , ray sidhi kyu chli gyi??
because ray was falling on normal
Light passing through Optical center of lens is considered normally
Sir aapka intajar tha bohot wait kiya sir
Bahut acha laga siry
Keep this brightness...🥰🥰🥰
Sir you explain all topics very clearly amazing class .. thank you sir 🙏
Sir your explanation is very clear my self ujjwal tiwari in live jaunpur
When we incident the light ray on the centre of curvature of concave mirror it gets deviated with same path why? Plz give answer
any ray passing through the centre of curvature is normal to the mirror surface.. because of which the angle or reflection and incidence are 0 degrees. I hope you get it
I m in 11th btw😂thought to help a Jr. 🌼
@@vanshikasingh5697 yupp..u r correct
@@abcd4872 i know that🤣itna confidence toh h..thoda sa pr hai
Sir ye bhi puchne ki baat hai kya ki maza aaya ya nhi
Aap padhate ho to mujhe lagta hai ki esa same interest mereko school k online class me kyu ni aata😅
Thanku very much sir love u so much ❤❤❤❤❤❤❤❤❤❤
RULES FOR OBTAINING IMAGE IS SPHERICAL LENS :-
1] Ray parallel to principal axis will pass through focus (right side for convex lens and left side for concave lens).
2] Ray passing through focus on left becomes parallel to principal axis after refraction.
3] Ray passing through optical center will emerge without deviation.
Hii
Sir mujhe ek question mein doubt hai kya aap mere is doubt ko solve karenge ,ha to doubt ye hai ki apne reflection through spherical mirrors mein bataya tha ki concave lens converge karta hai aur convex lens diverge karta hai lekin yaha pe aap (rules to obtain image) point mein apne kaha hai ki convex lens converge karta hai aur concave lens diverge karta hai aur isme mujhe bahut confusion ho raha hai aur yahi mera doubt hai sir mere question ka answer jald hi dijiyega sir ye meri request hai aapse kyunki main apne exam ki taiyari kar raha hoon aur ek do mahinon mein . I respect the physics wallah foundation RUclips channel ,thank you sir
