Find t equations. the location and of the i M : An object with a height of 42 cm is placed 2.2 m in front of a convex mirror with a focal length of -0.42 m.

(b) Is the image erect or inverted? erect O inverted (c) What is the focal length of the mirror?

Explanation / Answer

Given,

Focal length, f = 0.75 m

Object distance, u = 2 m

Height of object, ho = 42 cm

a) using mirror formula

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

(1/ 0.75) = (1/ v) + (1/ 2)

Image distance, v = 1.2 m

b ) magnification of the image, m = - v / u

m = - 1.2 / 2

Magnification, m = - 0.6
