Determine the correct value below.
a. Write the expression for the magnification produced by a lens in terms of object distance and image distance.
The formula for magnification is
b. A \(5\ cm\) tall object is placed perpendicular to the principal axis of a convex lens of focal length \(28\ cm\). Calculate the size of the image formed, if the distance of the object from the lens is \(8\ cm\).
The lens formula is
The value of image distance is \(cm\)
The size of the image is \(cm\)
[Note: Enter the answer upto two decimal places.]
