An object is placed 39cm from a certain mirror. The image is half the size of the object, inverted, and real. Part A How far is the image from the mirror? Follow the sign conventions. Part B What is the radius of curvature of the mirror? Follow the sign conventions
u = 39 cm
m = -1/2
we know, m = -v/u
-1/2 = -v/u
v = u/2 = 39/2 = 19.5 cm
1/f = 1/u + 1/v
1/f = 1/39 + 1/19.5
f = 13 cm
R = 2*f = 26 cm

spherical concave mirror has a radius of curvature of 20.0 cm. An object is placed 15.0 m from the mirror. Locate and characterize the image, i.e. tell how far it is from the mirror, on which side of the mirror it is located, is it real or virtual, is it enlarged or diminished, is it erect or inverted? Image is located_ cm to the right/left of the mirror vertex, is real/virtual, erect/inverted, enlarged/diminished (circle your choices)
5. An object is placed 20.0 cm in front of a mirror and a real, inverted image is detected a distance of 30.0 cm in front of the mirror. (a) What is the radius of curvature of the mirror? (b) Draw a (somewhat to scale) ray diagram showing the mirror, object, and image.
