Lens formula=1/f=1/v-1/u
Mirror formula=1/f=1/v+1/u

19:39 this question directly came in jee mains 2023😮

[@sianveerkaur083]

In boards also

[@funatsun]

at 10:10 ,sir why object distrance is -ve when in lens in left side its R2 which is considered as positive

[@sdphysics100]

Virtual object negative
Real object positive

[@NEET2027-po7it]

Virtual object = +ve
Real object = -ve

[@Heisenberg063]

Sir or question kraiyee please 😢

Plz check the playlist

[@shubhraj5343]

Sir pehle wale question me apko yeh kaise pta chla ki focus se 20cm dur image banegi
3:30 pe

[@sdphysics100]

Parallel beam h
To focus (20cm) pr converge hoga

Sir book name plz

Do Practice of previous 10yrs paper of CBSE of different regions.
Youcan get them from regional sites of CBSE.

[@RAVIRAJ....]

Sir first question me formula aap ne mirror formula lagaya lekin aap lens formula bol rahe the ?

[@sdphysics100]

Thank you Raviraj chahar for your keen observation.
I applied the mirror formula but speak it lens formula.
It was a routine mistake, i admit it.
Onece again thank you very much to point out this mistake.

[@RAVIRAJ....]

Can u plz tell me the time stamp ,where i used this for lens

[@sdphysics100]

@Conceptual PHYSICS You know that a lens has two spherical curved surfaces. Here 2f is centre of curvature of individual curved parts of Lens.
