A concave mirror (f = 44 cm) produces an image whose distance from the mirror is one-fourth the object distance. (a) Determine the object distance. cm (b) Determine the (positive) image distance. cm

Solutions

Expert Solution

Focal length f = 44 cm

Image distance v = ( 1/ 4) Object distance

= u / 4

we know ( 1/ u ) + ( 1/ v ) = ( 1/ f)

( 1/ u ) + ( 4/u ) = ( 1/f)

5 / u = 1/ f

From this distance of the object u = 5f

= 220 cm

(b). Image distance v = 55 cm
