1.concave mirror,,,,2. Real and inverted,,,,3. -40cm,,,,,,4.object is at centre of curvature 😊😊
+40 hoga

Why sorry then 😅
@@Lakshya-im4u respect bro

iv - at c of curvature
1. Concave mirror 2. -40 cm 3. real inverted same size
why concave
@@atharv7724 because concave mirror mai hi ban sakti hai image jo magnifaction -1 wali ho. Ek toh same size hai image ka [m=1 matlab hi =ho] aur minus sign hai which indicates ki real and inverted hai [not possible in convex mirror]
MIRROR- Concave mirror
Real, inverted and the same size as the object
u= -40cm
third ray diagram of concave mirror
1 converging mirror
2 real and inverted
3 -40cm
4 object postion=centre of curvature and image position is also centre of curvature
Concave mirror
Real inverted and same size
u=-40 cm
Ray diagram will be at c one.
Sir Q3 Ka +60 apne - 60 kr diya Sir dekhiye --
M=-v/u
-3=-v/-60) (minus / minus Cut hogya)
-3= v/60
-3/1=v/60 (Cross Multiply)
(V= -60) Answer ✅
ABHISHEK SIR Please take the PYQ session of electricity and magnetic effect as well
1-concave mirror
2-real,inverted,same size
3- 40cm
6:59 Sir answer 40cm hoga kyuki object se screen ke beech me distance pucha hai
how
Noo, because the image is formed on the screen . Image distance is asked
@udayedits
Ur correct bro because they are not asking distance of image from mirror .they are asking to find the image distance from object
I clicked on the video ignoring 'CBSE' written, hoping it would prepare me for the internal reflection ,Prism, Spectrum and dispersion numericals for ICSE...... But you know what there is almost no content on ICSE syllabus like this (PYQs ,etc) I am doomed
Yes sir please conduct a similar session for the other chapters
1:37 save time
Amazing session sir❤
Answer:
i) Concave mirror
ii) nature is real image
iii) object distance is 40cm
For other chapters also we need sessions like this.
Balle balle 🔥🔥
Thank you sir
hw-
1) concave mirror
2)real inverted and of same size (3rd ray diagram)
3)u= -40cm (same)
btw sir , aapko yaad hai ye same question mein offline marathon mein board par solve kiya tha along with the ray diagram aur aapne tareef bhi ki thi❤✨ can never forget that moment!
1 concave mirror
2 real and inverted
3 -40 CM
Last question answer:
1) Concave mirror
2) Real and Inverted
3) 40 cm i.e. object is on center of curvature
4) Yah! You can make this easily 😅
Please like if u want ❤
Edit: If any mistake in my answer pls. tell me😃
-40 cm hai bhai
concave mirror u = -40 focal length = -20
1. Concave mirror
2. Image is real, inverted and same size
3. Object distance is -40 cm
Attendance for 2024-25
Last question answer:
1 . Concave mirror
2. Real and inverted
3. 40 cm
Tq sir
Pls do the same for the rest of the
Chapters
Please do it for the rest of the chapters ..As well... Thank you
Sir, I have a doubt... at 11:07 , the answer is given as 3 but you said it is 1. Can you please explain why is it so sir?? Please sir😢
Yes sir ... I too observed that option 3 is correct
Me too
Actually option 1 is correct but it was shown wrong that 3 is correct...
Angle of i > angle of r in a glass slab
6:52 sir 40cm hoga 'distance from object' pucha he ~ Ojal K.
how
Sir in question 3 there is a case 2 also right, where m=+3 since if u place a object between F and P we can obtain a virtual image, ans = -60cm and 60cm
Virtual image cannot be obtained on a screen
Concave mirror , real inverted , same size of the object. U=-40 cm . Third ray diagram of concave mirror
Sir 14:43 me value of focal length nikalna possible nai hai kiuki 2f=r sirf mirror keliye hai lens me work nai karta
chu
(i) Concave mirror
(ii) Real, inverted and same size
(iii) -40 cm
Sir some topics that you included are not in the syllabus
Like - angle of emergenc

Jai shree Ram
Lol
U=-40cm third ray diagram v=-40cm concave mirror
1:33 video start from
Yes sir do it 😊
ram ram sir
⁎ concave
⁎ real, inverted
⁎-40cm
6:46 , yaha pe sir (-3)*(-20)= +60
Hoga n sir
More questions pls❤❤
Tq sir now I am able to solve the numerical without any confusion
Sir we want repeated pyqs from other chapters also🙏🏻❤️
In question 8, the u should be -38 as u said u is always negative??!
for all chapter
Sir question no.8 ke 3rd part me apne virtual erect btaya h but wo real and inverted hoga kyuki wo real rays se bna h
Sir ji u have done 6 no. Question wrong according to vedantu itz option 3. St this option the green light occured but u didnt noticed it. So i request u to look after this question ❓🙏
Plz sir sabhi chapters ke mix PYQ in one vidoe

YES TOP 20
QUESTIONS
Sir iski pdf kha milegi and awitu solutions plz reply
6:45 sir - × - = +
Yes sir please
Please do similar questions for magnetic effects and electricity
The session was really amazing .. now I am feeling very confident ❤️🔥🔥
Sir please make a video for the other chapters also...... please sir
6:56
Thanks sir
Always favourite 😊😊 thank you sir😊❤
Sir 7th Feb ke baad daily handwritten notes ka section update hi nahi hua😭

Sir please ak full science all chapter important MCQ ki video Kara do 🥺
Sir how to download this pyq because you were in between i was enable to see answers
9:50 Sir usse greater than -10 par less than 0 hona chahiye par aapna less than -10 łikhá hua hai
1. Concave
2. Real and inverted
3. -40
Thank you sir for this session .
Science ka exam phod ke aayenge
Bhai podh nhi phod hota hai 🙂👍
Sir, mujhe kal ke liye apka dimag chahiye 🥺🥺🥺
Pls mna mat kerna 😂😂😂😂😂
Aab to bhai Top maraga😂
Yes sir we want
Yes sir plz do it chap.-magnetic field and electricity
Yes sir karva do❤
Yes sir
11:07 😮😮😮
Exactly, sir said first option is correct but in the slide it can be seen that 3rd one is correct
Actually that man (sir) is correct maybe there is a mistake while making the slide show
Very imp lecture 💯💯💯🔥🔥
Sir aap no. 6 check kijiye
Sir -60❌ 60☑️
wish everyone pass....
Thanks Sir ❤❤❤❤
Welcome 😂
Sir 1st Wale ka answer 40cm hoga kyon ki object aur screen ki distance puchi hai
We want electricity and magnetic questions 💥
Sir please make such video for electricity
Yes sir, aap le krr aau aise videos
Sal bhar kya Kiya Jo tum exam ke pahle dekh rahe ho 😂
Ye badiya tha dude😂😂
10 months are left
Bhai me exam ke din dekh raha hu
3rd question answer is 60 cm not-60 cm
All the questions are copied and taken from Khan Academy's website ❕❗
Sir 😊read the first line at lost in front of 🧐🤔it is always ...........means 😊
Question 4
Sahi me question repeat hota h CBSE me😮😮
The q 2:43 question will come in boards 2024-25 100%
Sir need more ch pyqs
😂Fantastic
Sir 3. Ka answer +60 hoga
Yes boy
You are right
@priteshnayan6 good job
Vote for more pyq
Next toppers vale like kro
Please one shot for all physics chapters
1. Concave mirror because magnification of image in concave is always negative.
2. Real and inverted because more than 1. So it's is real.
3. It at centre of curvature because magnification of 1 is always same size.
OR
We can solve it to m= -v/u
m= -(-40)/-40 = -1
So magnificent -1 so same size. At centre of curvature
Sir we need pyqs of other chapters also
Check the pdf link mention in the discription of the video
Sir answer ko dikane ke ia kuchh second ke lia side ho jaya karia please🙏
Ok try krta hu sir
Sir plz change light position in your studio
1000
Sir third question
Yes sir plls make those videos
Sir 10 most repeated question for rest chapter as well👍
