Use lens formula

1/v-1/u=1/f? that one?
anonymous
  • anonymous
Object distance = -u image distance = v Height of image / height of object = v/u

hi/ho=-v/u

can u do it?
anonymous
  • anonymous
yeah
King
  • King
yeah as in can u post the sol.?
anonymous
  • anonymous
see now, h / 2h = v/u u = 2v
King
  • King
ok
anonymous
  • anonymous
\[1divv -1divu =1divf\]
King

\[1/v-1/u=1/f\]

King
  • King
why is it -2v?
anonymous
  • anonymous
Becoz, in calculation, u should take object distance as negative. So, u becomes -u. And hence -2v
King
  • King
ok so u get 3/2v=1/f 2v=3f
King
  • King
after that?
King
  • King
aadarsh u der?
anonymous
  • anonymous
Then, equate v = 3f / 2
anonymous
  • anonymous
Substitute it in the formula: 1/v - 1/u = 1/f
King
  • King
i get u=3f
anonymous
  • anonymous
U r correct
King
  • King
so that it?
King
  • King
answer is -f
anonymous
  • anonymous
Yeah, soorry. Then don't use - 2v in the formula. use 2v. U may get it.
King
  • King
i get u=f

@aadarsh, u have successfully completed 10th so tell me, can a convex mirror produce an image which is half of the object's height?
anonymous
  • anonymous
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.
anonymous
  • anonymous
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
anonymous
  • anonymous
@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.
anonymous
  • anonymous
oh my! check ur 10th book aadarsh
anonymous
  • anonymous
didi, its given that it will form a diminished, virtual and erect image. That's all na?????????
anonymous
  • anonymous
ya so will it produce a half-sized image?
anonymous
  • anonymous
not really. BUt can it not produce in some cases???????????????
anonymous
  • anonymous
i am curious when? when our bible says no it is a no u know wat i mean by bible dont u?
anonymous
  • anonymous
Yeah, "Bible" means Book. (NCERT) Can u plz say why it cannot?
anonymous
  • anonymous
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?
anonymous
  • anonymous
whenever u see a question related to lens or mirrors flash the image formation diagrams b4 the formula @king ur question is wrong
anonymous
  • anonymous
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.
anonymous
  • anonymous
:) see ur text book and read my last comment it will help u
anonymous
  • anonymous
Yeah, u r rite didi. I was mad at the first itself.
