An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. What is the image height? (Indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10

image height is -1

Explanation:

1/f=1/v+1/u

1/f-1/u=1/v

1/5-1/10=1/v

10/50-5/50=1/v

5/50=1/v

1/10=1/v

v=10

v=u

implies , object is at c and image is formed at c

therefore this case is in concave mirror

image formed is virtual n erect so image height is negative

h/hi=v/u

h/hi=10/10

1/hi=1

therefore hi=1

as height is negative

image height is -1
