Use lens formula
1/v-1/u=1/f? that one?
Object distance = -u image distance = v Height of image / height of object = v/u

hi/ho=-v/u
can u do it?
yeah
yeah as in can u post the sol.?
see now, h / 2h = v/u u = 2v
ok
\[1divv -1divu =1divf\]
\[1/v-1/u=1/f\]
|dw:1332858999064:dw|
why is it -2v?
Becoz, in calculation, u should take object distance as negative. So, u becomes -u. And hence -2v
ok so u get 3/2v=1/f 2v=3f
after that?
aadarsh u der?
Then, equate v = 3f / 2
Substitute it in the formula: 1/v - 1/u = 1/f
i get u=3f
U r correct
so that it?
answer is -f
Yeah, soorry. Then don't use - 2v in the formula. use 2v. U may get it.
i get u=f
ok.thnx gtg!1
bye
Oooooooooooo. Gtg. Byeeeeeeeeeee. ur result?
in what 9th .....94.83%
kk bye!
Super. Congrtas. Ready for US trip?????????????
yup!
PLz reply to my email. plzzzzzzzzzzz
ok
Byeeeee
@aadarsh, u have successfully completed 10th so tell me, can a convex mirror produce an image which is half of the object's height?
Arre Shalini didi and king, I think I was in a dream while solving this question. I thought it to be a convex lens instead of a mirror. Here is the detailed answer. Sorry for mistake.
Mirror Formula: 1/v + 1/u = 1/f And, h'/h = -v/u (magnification formula) So, given, h'/h = -v/u = 1/2............(i) So, u = -2v.......(ii) Now, 1/v + 1/(-2v) = 1/f Or, 1/2v = 1/f Or, f = 2v Or, f = 2v So, f = -u [From (ii)]
u havent answered my question yet aadarsh can a convex mirror , produce an image which is half of the object's height? i wud like to add one thing here be very clear to visualise the ray diagrams for any lens or mirror b4 solving sum
@salini akka, i think a convex mirror can produce an image half size of that of object, in some cases, when object is between infinity and pole of mirror.
oh my! check ur 10th book aadarsh
didi, its given that it will form a diminished, virtual and erect image. That's all na?????????
ya so will it produce a half-sized image?
not really. BUt can it not produce in some cases???????????????
i am curious when? when our bible says no it is a no u know wat i mean by bible dont u?
Yeah, "Bible" means Book. (NCERT) Can u plz say why it cannot?
its the property of convex mirror to always form virtual diminished(not even the quarter of size of object)_ how? it was found by great ppl all we do is read them right?
whenever u see a question related to lens or mirrors flash the image formation diagrams b4 the formula @king ur question is wrong
How didi? question is wrong? See my process . Everything is correct. But u r true taht a convex mirror cannot form an half image image.
:) see ur text book and read my last comment it will help u
Yeah, u r rite didi. I was mad at the first itself.
