Title: Which diagram shows the image formed behind the mirror?
Post by: NotAbod on May 13, 2011, 07:34:54 pm: hey :P
this question is usually asked in the question papers, and we pick the wrong answer (wooooooot)
why? because we dont have a mirror.
who said so? u can make ur own mirror :P
see that pic in attachments, it explains everything :P
use ur calculater screen as a mirror. and try to get the image of the object on it.
in the question if the mirror is on the right side, then put the calculater on the same side, not on the opposite side :P
in this case (attached pic) mirror is on the right side.
this method is Dedicated to my physics teacher Mrs.Nahla, a great teacher!
hope this helps :P

i used to use either specs, calculator or watches ;)
Its great for many others :)

nice, u try to use ur watch in solving physics, not only to know wat time is it :P

Guess what i also use in transformation thing in maths :P
The reflection part :P

used ur specs for reflection in transformations too? why not tracing paper?

tracing paper is for some other work :P
rough work to find diff methods for the same solution ;)

i find it easier to use tracing paper for all transformations, except translation, shear, stretch and enlargment

Well i use tracing paper only for rotation :P
Are you ready with physics and maths?
