2. A 112,5 cm tall light image is placed at a distance of 75 cm from a concave mirror with a focal length of 25 cm. Calculate the object distances, its magnification and the object,s height

3. A concave mirror has a focal length of 10 cm, and an object is placed 15 cm from the concave mirror. Determine the distance of the image from the mirror, and the characteristics of the image

1. An object is placed at a distance of 20 cm from a convex mirror with a focal length of 60 cm. Determine the image distance and magnification.

2. An object is placed at a distance 30 cm from a convex mirror, and an image is placed at a distance of 15 cm. Find the magnification and the focal length of mirror
