A real image is formed by the light rays after reflection or refraction when they:
(A) actually meet or intersect with each other.
(B) actually converge at a point.
(C) appear to meet when they are produced in the backward direction.
(D) appears to diverge from a point.
Which of the above statements are correct?
(a) (A) and (D)
(b) (B) and (D)
(c) (A) and (B)
(d) (B) and (C)
Answer
To form an image light rays must
- Converge at a point
- Meet somewhere, and
- Intersect at some point.
Thus, option (A) and (B) are correct.
So, the correct answer is (c)
Note : If an image appear to meet when they are produced in the backward direction, then it’s a virtual image ( Check example )
