A tall object is placed in front of a mirror. A tall upright image is formed behind the mirror, from the object. What is the focal length of the mirror?
The focal length of the mirror is .
We have given,
Height of the object =
Height of the image =
distance between he object and image =
We have to find the focal length of the mirror.
Magnification of the mirror
we know that
Using mirror equation
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 .
