Question

A real object is located at the zero end of a meter stick. A large concave mirror at the 100 cm end of the meter stick forms an image of the object at the 72.5 cm position. A small convex mirror placed at the 20.6 cm position forms a final image at the 10.0 cm point. What is the radius of curvature of the convex mirror?

Answer 1

1/F = 1/(72.5-20.6)+1/(-(20.6-10))
-> F = -13.3
-> C = -26.6

Good luck with your Physics exam :)
