reflecting, spherical Christmas tree ornament has a diameter of 9.0 cm. A child looks at the ornament from a distance of 12 cm. Describe the image she sees.

Verified Answer :

f = R/2

(9/2)/2 = 2.25 cm


i = 1/(1/f - 1/o)

1/(1/2.25 - 1/12) = 1/2.769 ⇒ 0.36

I believe the image would appear upright.

The distance of the image observed by th girl is 2.77 cm.

Focal length of the lens

The focal length of the lens is calculated as follows;

F = R/2

where;

  • R is the radius of lens

R = 9 cm/2 = 4.5 cm

F = R/2

F = 4.5/2

F = 2.25 cm

Image distance

The distance of the image observed by th girl is caculated as follows;

1/f = 1/v + 1/u

1/v = 1/f - 1/u

1/v = 1/2.25 - 1/12

1/v = 0.3611

v = 2.77 cm

Thus, the distance of the image observed by th girl is 2.77 cm.
