@gudden
I think you should post an example (of your choice) and solve it with us. We can then see where are you facing trouble. :)

Answer 7

okay.. for example... if an object's image appears to be magnified by 2x when placed infront of a concave mirror.... find the position and nature of the image

Answer 8

@ gudden
do you know the formula of magnification ??

Answer 9

ofcourse.....

Answer 10

So, you'll get two equations between v and u
one from magnification and other from mirror formula..

You can solve for v and u

Answer 11

yeah... i do get,...... alright...... :D

Answer 12

So where do you face trouble ??

Answer 13

Answer 14

In this example; you solved for v and u using m and f..

Answer 15

But you can draw an approximate ray diagram simply by looking at the pattern of the mirror / lens

Answer 16

There was a table in ncert ; as far as I remember..

Answer 17

You can use it to make the ray diagram without doing the actual calculations..
