A 4.50 cm diamond pendant is placed 28.0 cm in front of a spherical mirror. It is desired to produce a virtual image that is erect and 3.50 cm tall.
a. What type of mirror should be used and why?
b. What is the magnification of the image formed by the mirror?
c. Where is the image located? (Find the image distance, .)
d. What is the focal length, f, of the mirror?
e. What is the radius of curvature, R, of the mirror?
f. Draw a scaled and carefully labelled ray diagram to locate (approximately) the position of the image using the grid and identify its characteristics (S.A.L.T.).
