If your nose is 20.0 cm from a convex spherical mirror having a radius of 100 cm,

 

 

    1. = Locate the image

 

do=3D 20.0 cm

 

f =3D - 50.0 cm

 

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

 

1/di =3D 1/f -  1/do 

 

1/ di =3D 1/(-50.0 cm) - 1/(20.0 cm)

 

di= =3D -14.3 cm

 

    1. = Find the lateral magnification.

 

 

M =3D - di /do =3D - (-14.3 cm)/(20.0 cm) =3D 0.714

 

 

    1. = Describe the image (real or virtual, enlarged or reduced, upright or inverted)= .

 

Virtual (di <0), reduced (|M| <1), and upright (M > 0)
