A 2.00-cm-high object is placed 70.0 cm from a convex-concave lens. The convex surface of the lens has a radius of curvature of 40.0 cm, the concave surface has a radius of curvature of 30.0 cm, and the index of refraction of the lens material is 1.70.

a) Calculate the focal length of the lens. b) Is the lens converging or diverging? c) Where does the image appear, relative to the lens? d) What is the height of the image? e) Is the image real or virtual? f) Is the image enlarged or reduced in size? g) Is the image upright or inverted? h) Draw a ray diagram.
