Ray Optics and Optical Instruments

  1. Match the corresponding entries of column-1 with column-2 (Where m is the magnification produced by the mirror) : ​​
    Column-1 Column-2
    (P) m = – 2(A) Convex mirror
    (Q) m = - 1 / 2 (B) Concave mirror
    (R) m = + 2 (C) Real image
    (S) m = + 1 / 2 (D) Virtual image
    1. P → B and C, Q → B and C, R → B and D,S → A and D. ​
    2. P → A and C, Q → A and D, R → A and B, S → C and D
    3. P → A and D, Q → B and C, R → B and D, S → B and C
    4. P → C and D, Q → B and D, R → B and C, S → A and D
Correct Option: A

Magnitude m = +ve ⇒ virtual image ​m = –ve ⇒ real image ​
magnitude of magnification, ​
| m | > 1 ⇒ magnified image ​
| m | < 1 ⇒ diminished image
