1. Initally keep the convex mirror and convex lens at any distance apart from each other, but it is better if it is not too far apart. 2. Now take the object and adjust it such that the parallax is removed. 3. Once done, remove the mirror and again adjust the other pin such that parallax is removed 4. Find value of R 5. For next observation, do not change position of lens, instead bring the mirror a bit closer (around 2 cm) to the lens and repeat the experiment. P.S: My practicals are over and I got this experiment. But thankfully I got good readings.

@@optimistic20027 lmao examiner bhot hi lenient tha aram se cheating ho rhi thi aur viva ke question bhi ek dm asan asan puch rha tha sbse infact mujhse to viva bhi nhi liya😂 kehta bs diagram sundr bna lo tumhara vhi viva ho gaya😂😂
so basically we keep the mirror at an arbitrary position and with respect to this position we adjust the lens and the needle on the right, after which we remove the mirror and keep the lens and needle on the right constant, we adjust the needle on the left and take readings?
we have to position the object needle between the focus and radius of curvature...so if we multiply less than equal to 1, we will not get the appropriate position...similarly if we multiply more than 2, it will go beyond radius of curvature... You can multiply any number between 1 and 2...but just to get a round figure, we usually multiply 1.5

Thanks bhai ..bahut confusion tha
@@ItzSiddhant 😂😂😂
Bhai object ko kitne distance pe rakhna hai?
R is measured from the mirror? or lens?
People seeing this video a day before exam hit like😂😂👍👍
I swear 🙄😭
Bhai kl practical h or teacher sae ldai ho rkhi ...ek v experiment class attend nhi k😫😫😫😫
Yup😂
Seeing this 2 hours before exam.
hmmmm
I have board practical 2 hrs later, thank you sir to help me revise
kaisa gya bhai?
4 hrs later
Bhai tum toh mtlb..
Ultra legend ho
M bhi ab dekhra bro lens lens ka dekhunga junction ye sab to ata ni h
Congratulations your practicals had got cancelled
I have my board praticals tomorrow and i am seeing this right now. Very helpful to revise sir
Seeing this video doing my boards practical 😎 seriously 😸

THIS VIDEO IS LIFE SAVER SIR THANKS SOO MUCH
Salute to cameraman.
Thanks sir for helping . With this and other videos on optics my doubts are cleared
I watching this video in practical exam 🗿

Abe hamare to ho hi nhi rahe hain
Hmare kal h aur main 3 am ko dekh ke cram krne ka try kr rha hu :'D

Nicely explained, thank you.
Very well explained Sir, thank you so much! :)
Sir before removing mirror where we have to keep the image pin?
Yo sirrrr U rock
sir jo kabhi samajh ni aaya apne vo samjha diya
Thank U Sir
please keep making educative videos
Tomorrow is my practicle exam nd I had many doubts. Thanks sir for this vedio it really helped me.
same here bro, gn mein ho kya??

How much distance should be taken between lens and mirror ?
Plzz reply kl practical hai😭
Kaisa gya?
Lmao
Who all seeing this video having physics final practical tomorrow are really legend
Watching this video before my exam 😂
😂 Me too
Bhai Mera 2years baad physics ka practical h esliye ma abhi se practice kar raha hu
amazing experiment sir....thank you sir.....for this amazing video...
Thanks for this great explanation ❤️❤️🙏
I have my board practical after 10mins now I am outside my school😂😂🤣
Why do we multiply with 1.5?
UA-cam is the real savior for the students.😁
Convex Mirror and convex lens ke beech me kitna distance hona chahiye?
kcuh bhi rakho 45-55 ke beech jyaada far nhi
Thank you sir ji🙏🙏
Its awesome
It is very helpful for my practical tomorrow
Legends watching in the school 😂😂😂😂🤣
Who was watching this video after a practical exam😅😅
Thank You Sir. This was really helpful ♥️♥️
I don't know you.
the explanation is so good
The guy looks good i mean that kid who we could see in the mirror 😅
Thanks sir I have final practical tommorow
1:29 legendary cameraman spotted!
Chup kar be
lmaooo
Sir, why have you put the convex mirror at 47.7 cm?
Any specific reason to do so?
You can place it anywhere close to convex lens
Nice video sir
Visual Physics Tutor why did you find focal length of convex lens bcoz in question its asked focal length of convex mirror using a convex lens ???
From Brijesh Garg RPS 🤣🤣🤣🤣🤣🤣🤣
thank you SIR!!! it is very usefullllll.
thanks a lot sir....
I am seeing it on my way to school😂😂
2morow is my phys term2 practical 😅👍🙏wish me good luck
Guess who's got the practicals this morning
Me
Kuch nhi aata + activity file pura nhi kiya lmao
1:32 that boy in the mirror: ' oh look look I am on youtube ..... I am a celebrity'
lol
Ma'am hain woh shayad
so basically we keep the mirror at an arbitrary position and with respect to this position we adjust the lens and the needle on the right, after which we remove the mirror and keep the lens and needle on the right constant, we adjust the needle on the left and take readings?
hey bro, best of luck for the exam!!
@@krithikchandran4647 xd bro
@@ashishmohan4683 😂
yes
Ye object pin ko 1.5× focal length of convex lens pe kyu rakha gaya hai ?
Rough focal length was 18.5 CM then why we have kept convex lens at 55 cm??
The rough focal length is 18.5 cm, so from 55 cm, the pin is placed 18.5 cm apart
Focal length of lens will determine the object position(ie, we will place the object outside focal range), lens position is arbitrarily chosen.
Watching before 20 mins of my practical exam 💀
Thank you
You were a great help
Great clarify experiment
Kl h mera pratical thz sir ji❤️🔥👑
Why did you take 1.5 times of the focal length of convex lens
Here it means between f and 2f case
Same question
Thank you sir you made my practicals easy to a great extent🙏🏻🙏🏻😇
Hii
Who else seeing this 2 minutes before board practicals m
Good explanation but instead of using english use hindi for explanation
Thanks sir 🙏
Sir isme x ka value kase nikle gaa video hoga to bezna
Thanks a lot. Because of you I understood it well😀
Sir you helped me👍❤
Ye saare optics ke practical ek jaise kyu lag rahe hai? 🤔😮💨
What should be the range of focal length of the lens sir?
It should be around 45-55cm
less than 20cm
Sir why 1.5 is multiplied withthe rough focal length?
we have to position the object needle between the focus and radius of curvature...so if we multiply less than equal to 1, we will not get the appropriate position...similarly if we multiply more than 2, it will go beyond radius of curvature... You can multiply any number between 1 and 2...but just to get a round figure, we usually multiply 1.5
Draw the ray diagram.. U will get it
Now the camera man also know to find the focal length of a convex mirror using convex lens
Thank u sir... it's very useful..
Thank you 😊 very much sir
Very good explanation sir👍
Here 1 day before my Term 2 Practicals
8:50 ho rahe hain mai school mai dekh rha hun or 9:40 par practice start hone vaala hai
Can I keep the object needle at 2f
Why should we keep it at 1.5 times f
Thank you very much sir.👍👍👍👍
I have practical tomorrow
Bhai mera bhi kal hai 😂
Practice exam k time examiner practical Notebook dekh k practical perform krne dete h kya???
@@bhavyakumari2483 where are you from and in which school you are..?
Can we keep the convex lens at any distance from mirror initially?
Yes; prefereably towards the middle

Wht is actual length of needle?
it depends sir or maybe 10 cms
