a real image 9cm from mirror is formed when object is 14 cm away from mirror. if object is 20cm away, where is the image?

Expert Solution

Here, first clue is the image is real. Information leads to find out the mirror is concave. First we need to work out what is the focal length of mirror. By using equestion one and the image distance, Object distance for case focal length of mirror has been found out.

After finding out the focal length the image distance has been found out by using the object distance for second case and equestion one.

When an object is located very far away from a convex mirror, the image of the object is 12.0 cm behind the mirror. Using a ray diagram drawn to scale, determine where the image is located when the object is placed 6.0 cm in front of the mirror. Note that the mirror must be drawn to scale also. In your drawing, assume that the height of the object is 3.0 cm. cm ---Select--- in front of behind the mirror As an...
