Challenge Problems
Push your limits with advanced challenges
A convex mirror has a focal length of -20 cm. If an object is placed at a distance of 30 cm, calculate the image distance and describe the nature of the image formed.
💡 Hint: Remember that convex mirrors only produce virtual images.
A concave mirror forms a real image of an object placed 15 cm from it. If the mirror's radius of curvature is 40 cm, determine the image distance and nature of the image.
💡 Hint: Real images are formed beyond the focal length.
