Question

an object is 36.0 cm in front of concave mirror with 16.0 cm. focal length. Determine the image position.​

Answer 1

11.07

Explanation:

Given:

object distance(u)=-36

focal length(f)=16

we know that,

1/v + 1/u=1/f

1/v=1/f - 1/f

1/v=1/16 - (1/-36)

1/v=1/16 + 1/36

1/v=9+4/144

1/v=13/144

V=144/13

=11.07

Therefore image distance(v)is 11.07
