A small kitten finds itself 150 cm in front of a concave mirror with the radius of curvature of 100 cm.

 

    1. Find = the image distance.

 

do=3D 150 cm

 

f =3D + 50.0 cm

 

1/di + 1/do=3D 1/f

 

1/di =3D 1/f - 1/do =3D 1/(50.0 cm) - 1/(150 cm) =3D 2/(150 cm)

 

di =3D 75.= 0 cm

 

    1. Deter= mine the magnification.

 

 

M =3D - di /do =3D -(75.0 cm)/(150 cm) =3D - 0.500

 

 

    1. Draw = a neat ray diagram of the situation.

 =

    1. Is the image real or virtual?

 

Real. (di >0)

 

    1. Is the image upright or inverted?

 

 

Inverted= . (M < 0)
