Match the corresponding entries of column 1 with column 2. [Where m is the magnification produced by the mirror] Column 1 Column 2 (A) m = - 2 (a) Convex mirror (B) m = - 1 2 (b) Concave mirror (C) m = + 2 (c) Real image (D) m = + 1 2 (d) Virtual image
Options
- AA → b and c; B → b and c; C → b and d; D → a and d
- BA → a and c; B → a and d; C → a and b; D → c and d
- CA → a and d; B → b and c; C → b and d; D → b and c
- DA → c and d; B → b and d; C → b and c; D → a and d
Correct answer
A. A → b and c; B → b and c; C → b and d; D → a and d
Step-by-step solution
m = - V u = f f - u m = - 2 then "V" and "u" same given - 2 = f f - u =- 2 f + 2 u = f = 3 f = 2 u + 3 f 2 = u For the concave mirror, f negative, u negative use same for all.
