1)An ____ lens is used to produce a real image.

A)convex
B)concave
C)plane
D)diverging

The link you gave me confused me b/c the closest thing I could find was convex. and you said concave mirrors produce virtual images. but the question doesnt ask for virtual they ask for real.

2)What is the nature of an image formed by a concave mirror of focal length 10 cm for a real object placed 3 cm from the mirror?

Virtual and inverted.

(10)(3)/3-10
