Later, when you look at the mirror from various distances from far across the room, you find that your reflection is inverted, but not always enlarged. (2 pts.) This mirror is: converging and concave converging and convex diverging and concave diverging and convex When your face is 10.0 cm away from the mirror, you find that its image has a magnification of +1.67. You do NOT need to show your work for this problem. Be sure to include units and sig. figs.! (3 pts.) What is the focal length of the mirror?## c. (2 pts.) What is the radius of curvature of the mirror?## a. (2 pts.) How far from the mirror should you put your face so that its image will have a magnification of -1 .67?##

Explanation / Answer

5. a. converging and concave

b. f=? u=10cm magnification m = -v/u = 1.67

v = 1.67 u = 16.7 cm

so 1/f = 1/u +1/v

f = uv/u+v

f = 1,67*16.7/(1.67+16.7)

f= 1.518 cm

b. radius r = 2f = 3.036 cm

c. if m=-1.67,

v = -1.67 u = -16.7cm
