Given the object distance and either the focal length or radius of curvature, determine the image distance and either the image height or the image magnification for convex mirrors.
The focal point of a convex mirror is located a distance of 36.7 cm from the mirror’s surface. Decide whether this means the focal length is + or -. Then calculate the …

The focal point of a convex mirror is located a distance of 34.4 cm from the mirror’s surface. Decide whether this means the focal length is + or -. Then calculate the …
… image distance (in cm) for an object located 12.5 cm from the convex mirror. Enter a – answer if the image is located behind the mirror.
Consider the convex mirror diagram at the right. The red arrow is the object. The distances A (object height), B (object distance) and C (focal length) are indicated on the diagram. Their values are:
A = 6.71 cm
B = 12.4 cm
C = 17.0 cm
Calculate the image distance (in cm). Enter a – answer if appropriate.
Calculate the image height (in cm). Enter a – answer if appropriate.
Image Height
A convex spherical mirror has a focal point located a distance of 26.4 cm from the surface of the mirror. (You will have to decide for yourself whether f is + or -.)
Find the image distance (in cm) for an object distance of 67.5 cm.
Determine the magnification of this image.
A large spherical mirror sculpture is constructed in the town square at Physicston, USA. The sculpture consists of a large sphere with a diameter of 25.2 meters which is coated with a reflecting material. A 1.52 meter tall photographer stands a distance of 37.3 m from the convex side of the sculpture and takes a picture.
Determine the image distance of the photographer. Enter a – answer if the image is located behind the mirror.
