An object is placed 15 cm from a concave mirror of focal length 10 cm, then the nature of the image formed will be
Options
- Amagnified and inverted
- Bmagnified and erect
- Csmall in size and inverted
- Dsmall in size and erect
Correct answer
A. magnified and inverted
Step-by-step solution
Given object distance u = -15 cm and focal length f = -10 cm. Using the mirror formula: 1 v + 1 u = 1 f 1 v - 1 15 = - 1 10 1 v = 1 15 - 1 10 = 2 - 3 30 = - 1 30 v = -30 cm Magnification m = - v u = - -30 -15 = -2 Since m is negative, the image is real and inverted. Since |m| > 1 , the image is magnified. Answer: magnified and inverted
