You are given a concave mirror by focal length 40.0cm. You start with an object 50.0cm high at 160cm in front of the mirror.
A) Draw the system and utilize the mirror equation to determine the characteristics of the image.
B) Now you move the object in toward the vertex of the mirror, ending by the object at a distance of25.0cm from the vertex. Give the new characteristics of new image and describe the behaviour of the image as the object moves to its final position.
