PHY136H5 Chapter : 268 The Thin-Lens Equation and the Magnification Equation

A 1.0-cm tall object is 10 cm in front of a converging lens that has a 30 cm focal length. Calculate the image position and height using the thin lens and magnification equations. 

Find the image distance and the magnification for a thin lens in air when the object distance is -23 cm and the lens is a converging lens that has a focal length of 23 cm.

Combine thin lens equations to show that the magnification for a mm lens is determined by its focal length and the object distance and is given by m=f/(f−do).
