A thin, diverging lens having a focal length of magnitude 50.0 cm has the same principal axis as a concave mirror with a radius of 60.0 cm. The center of the mirror is 20.0 cm from the lens, with the lens in front of the mirror. An object is placed 27.0 cm in front of the lens.

1. Where is the final image due to the lens–mirror combination? Enter the image distance with respect to the mirror. Follow the sign convention.

2. Suppose now that the concave mirror is replaced by a convex mirror of the same radius. Where is the final image due to the lens–mirror combination? Enter the image distance with respect to the mirror. Follow the sign convention.
