When an object is placed 10 cm in front of a mirror, an image is formed 45 cm behind the mirror. What is the mirror’s focal length?

Expert Solution

Solution:-

Given:-

do- 10 cm

di- 45cm

Formula for focal length:-

1/f = 1/d0 + 1/di

1/f = 1/10 + 1/45

1/f = 0.1 + 0.022

1/f = 0.1222 cm

The focal length of the mirror is = 0.1222 cm

You place a mirror 10 cm in front of your face, which creates an upright image that is twice the height of the object. You then move the mirror along the principle axis until it creates an inverted image twice the height of the object. What kind of mirror must this be and why? Where is the object with respect to the mirror’s focal length for each of the mirror positions? (ie. f < s < R) Draw ray diagrams...
