Convex mirror problem help??
a convex mirror has a focal length of 75cm. an object with a height of 2.0m is 6.0m from the mirror.
a) what is the distance from the object's virtual image to the mirror?
b) what is the height of the object's image?
1/f = 1/do + 1/di
1/0.75m = 1/6.0m + 1/di
di = 0.857m
but the answer should be -0.67 for a and i don't know part b
