1b) An object 0.75 m tall is placed 3.4m in front of a convex mirror that has a focal length of -80cm. i) Calculate the image distance. ii) Calculate the image height.

Answer 1

Plug in the numbers: 1/d_i + 1/d_o = 1/f Solve for d_i = fd_o/(d_o-f) (make sure lengths are in the same units.)

image height = ( object height) |d_i/d_o|
