# A -tall object is in front of a converging lens that has a focal length.Use ray tracing to find the position and height of the image. To do this accurately, use a ruler or paper with a grid. Determine the image distance and image height by making measurements on your diagram. Calculate the image position and height. Compare with your ray-tracing answers in part .

Part

The image distance is and image height is

Part

The image distance is and image height is

See the step by step solution

## Step: 1 Finding lateral magnification:

From thin lens equation,

The convex lens of focal lens is positive and concave lens is negative:the image virutal is negative and real image distance is positive.

The lateral magnification is

object height is

The lens is converging.

The distance lens object is

The focal length is

## Step: 2 Finding image distance: (part a)

The ray trace diagram is

From lens equation is

## Step: 3 Finding image height: (part b)

The lateral magnification lens by

By comparing, the both parts are agree.
