An object is located 75.0 cm in front of a mirror and on the principle axis. The mirror is concave with a radius of curvature 50.0 cm.
1. Please draw a ray diagram of the object, image, and mirror. Label the three principle rays.
2. State the properties of the image (real or unreal, upright or inverted, enlarged or reduced).
3. Find the location and the magnification of the image mathematically.
