A convex mirror has a radius of curvature of 26 cm. An object is placed 5 cm in front of this lens. Determine the magnification of the image formed by this mirror.
a. 0.72
b. 4.3
c. 1.76
d. 0.92
a. 0.72 is the correct answer.
given
R = 26 cm
focal length of convex mirror, f = -R/2
= -26/2
= -13 cm
object distance, u = 5 cm
let v is the image distance.
now use, 1/u + 1/v = 1/f
1/v = 1/f - 1/u
1/v = 1/(-13) - 1/5
v = -3.61 cm
magnification, m = -v/u
= -(-3.61)/5
= 0.72
