The radius of curvature of concave mirror is 24cm.object is placed at twice of focal length before mirror then find magnification
Answers
Answer:
Radius of curvature, R = -24cm
Focal length, f = - R/2 = - 24/2 = -12 cm
Object distance, u = 2 * f = 2 * (-12) = -24 cm
Let the image distance be denoted as “v” cm.
Using the mirror formula, we get
1/f = 1/v = 1/u
1/v = 1/f – 1/u
1/v = 1/(-12) – 1/(-24)
1/v = [-2 + 1] / 24
1/v = - 1/24
v = -24 cm
The magnification of the mirror is given as,
= - [v/u]
= - [(-24) / (-24)]
= - 1
