Best ResponseYou've already chosen the best response.2see now, h / 2h = v/u u = 2v

Best ResponseYou've already chosen the best response.2Becoz, in calculation, u should take object distance as negative. So, u becomes u. And hence 2v

Best ResponseYou've already chosen the best response.1ok so u get 3/2v=1/f 2v=3f

Aadarsh

Best ResponseYou've already chosen the best response.2Then, equate v = 3f / 2

Best ResponseYou've already chosen the best response.2Substitute it in the formula: 1/v  1/u = 1/f

Best ResponseYou've already chosen the best response.2Yeah, soorry. Then don't use  2v in the formula. use 2v. U may get it.

Best ResponseYou've already chosen the best response.0@aadarsh, u have successfully completed 10th so tell me, can a convex mirror produce an image which is half of the object's height?

Best ResponseYou've already chosen the best response.2Arre 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.

Best ResponseYou've already chosen the best response.2Mirror 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)]

Best ResponseYou've already chosen the best response.0u 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

Best ResponseYou've already chosen the best response.2@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.

Best ResponseYou've already chosen the best response.2didi, its given that it will form a diminished, virtual and erect image. That's all na?????????

salini

Best ResponseYou've already chosen the best response.0ya so will it produce a halfsized image?

Aadarsh

Best ResponseYou've already chosen the best response.2Yeah, "Bible" means Book. (NCERT) Can u plz say why it cannot?

Best ResponseYou've already chosen the best response.0its 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?

Best ResponseYou've already chosen the best response.0whenever u see a question related to lens or mirrors flash the image formation diagrams b4 the formula @king ur question is wrong

Aadarsh

Best ResponseYou've already chosen the best response.2How didi? question is wrong? See my process . Everything is correct. But u r true taht a convex mirror cannot form an half image image.
