1:19:56 sir 12 cm hona chahiye na.... 2 cm pr banegi total distance hoga 12cm aur phir 2nd mirror ke liye object ka kaam karegi toh waha bhii 12 cm pr banegi toh woh hogi na 2nd nearest
no, question dekho pehle. usme kaha hai second nearest image behind mirror A from the mirror A 12 cm's image is behind the mirror B so that's incorrect
Sir why are you teaching so good for free batch?
Really he is very kind and great teacher
Sahi baat ha bhai
Kyunki sir best hai ❤❤❤
@@KlyffHanger yea bruh ... He is awesome 💯
Sir ne optical instrument bhi ismein padhaayaa hai please reply
20) incident rays intersection ( object) & refected rays intersection (image)
21) For spherical mirrors-
VIx= - (v/u)²Vox
Viy= - (v/u) Voy
General formula at 2:09:01 ( imp) 22) refractive index = c/Vmed , = under root Er Ur
23) wavelength in medium = wavelength in air / U
24) ek medium mei wavelength aur velocity dono change hoti hai par frequency nhi , frequency depends on source
25) Usintheta=constant ( Uisini=Ursinr) 2:27:08 imp point related to this
39:45 reflection in vector form.
Sir hw question 1 ka 34 aaya
Question 2 ka 50 aaya aur bahut hi tamatar sa sawaal very easy
ha jo 4:11:15 pe diya tha uska mera bhi 34 aaya
Hw option aaaaaass🎉🎉🎉
12) parallel mirrors infinite images 13) remember short trick for images by ll mirrors ( dono ke bich ka distance add krdo diagonally) 14) concave mirror converging mirror & convex diverging ( lens ulta)
15) sign convention - incident ray direction +ve , upwards +ve, pole ko origin (0,0) lete hai
16) always focal length of concave mirror & lens - ve , convex - +ve
17) Vimp - power for spherical mirror = - 1/f & for lens 1/f
18) converging objects - power positive & diverging objects power negative
19) 1/f=1/v+1/u mirror formula
m = -v/u
1:43:03 magnification
Magnification real ya virtual nhi batatai wo m +ve means object sidha toh image bhi sidha ( same side) m -ve ( opposite side)
1:08:40 option B
Kese..? Mera to A aya
@@PalakPanwar-p6qMera c
C hoga
'A' WILL BE RIGHT
Thank you sir ❤❤❤❤❤
Koi time stamp daal dijiye please
Thank you sir
It helped me a lot
Sir aaj apne tamatar nhi bolaa 😂
4:09:41 pe tamatar bola sir ne... Tum kidar dhyan rakhte ho aspirant sahab
Ek baar aur bole hai starting ke 1 ghante ke andar
1:48:30 par phir se bole hai
Hw ans -
1:10:14 c)
a
50cm 4:18:32
Good class❤
4:11:16 - 34
Hw option A
Is it worth to watch if I am learning for first time
yes
Bale bale
1:19:56 sir 12 cm hona chahiye na....
2 cm pr banegi total distance hoga 12cm aur phir 2nd mirror ke liye object ka kaam karegi toh waha bhii 12 cm pr banegi toh woh hogi na 2nd nearest
no, question dekho pehle.
usme kaha hai second nearest image behind mirror A from the mirror A
12 cm's image is behind the mirror B so that's incorrect
