So first of all look at this img :
http://aycu35.webshots.com/image/31034/2003792274542358389_rs.jpg
OK now as u can see , there are 2 different lenses in the picture one is biconvex and the other one is biconcave . Since u already know that lets get to the point .
Since i am a novice in this catagory , and the teacher promiced to give an A+ to whoever solved this 1st , i beg you to help me find the FOCAL point in both cases .
Thank you all , cheers if u solved it . An img response with a little explaning will do very good .
