49:00 dont go with such long process, its very simple for TIR the light must travel from denser to rarer and for this case refractive index of water is not more than that of the prism. Thats so simple, dont get confused.
NO because when the light ray is passed from the second surface ie. AC then its passing through denser to rarer as prism R.I is more than water hence there are chances for TIR... so we need to check
1:24:36 answer v=60cm And 02:24:50 answer 26cm 2:33:50 f=50 cm and v=25cm Thankyou so much sir itne aache se samjane ke liya meri saari doubt clear ho gai iss chapter se aab

2:32:50 sir focal length=object distance hai to image highly magnified or infinity pr bnege...pr apke formula ke hisab se to wo 25 cm pr bn rhi hai aasa kyu ?
but observe the question carefully, it was written that is TIR possible for surace AC... which means when light travels through AC, now the situation is denser to rarer.. so we need to perform further calculations
2:06:09 The answer for part B is wrong if convex lens is kept in the path of beam then the point P acts as a virtual object for convex lens and thus will form a real image

1:05:38 I have a doubt in question no 15, Sir when light passes from rarer to denser then we use formula(sin ic = 1/u) but here ligh passes from denser to rarer n
Bro we use sin ic=1/u in the condition of T.I.R. and in T.I.R light rays travel from denser to rarer medium. That's why we have used this formula here.
but sir ne to mirror formula likha diya jabki baat to lens ki chalrhi he to image distance 25 kaise aya.. lens ka formula lagye ge to 0 arha image distance please koi explain kardu

NO because when the light ray is passed from the second surface ie. AC then its passing through denser to rarer as prism R.I is more than water hence there are chances for TIR... so we need to check
Exactly how will u explain this in boards because no matter what refractive index of prism is denser only...it won't matter that its slightly denser
n of prism is more than that of water so it is going from denser to rarer only

Hmm
Sir kya baat h aaj hi chapter revision kiya or pyq bhi aa gyee mja agya
1:24:41 Ans is v= 60 cm behind the mirror i.e. virtual and erect image is formed and magnified.
1:24:20
Position of image will be v= 60cm
Magnification will be 3
Image will be virtual , erect and magnified ,as magnification is more than 1.
1:24:13 V -> 60 cm image nature is virtual and erect.and manification is 3
1:03:22 sir when object is placed between f and 2f , image will be formed beyond 2f.
2:02:43 sir your answer is wrong
THE ANSWER WILL BE: -64
2:24:34 f' = 26cm 🫶
