This problem deals with lenses, please explain using equations, and ray diagrams.
A real object is at the zero end of the meter stick. A large concave mirror at the 100-cm end of a meter stick forms an image of the object at the 70-cm position. A small convex mirror placed at the 20-cm position forms a final image at the 10-cm point. What is the radius of curvature of the convex mirror?
The solution is calculating the radius of curvature of a convex mirror. The positions of object and the image formed due to the two reflections at a concave and convex mirrors. The ray diagram is given with the solution and the formation of the final image is discussed.
