| The direction of ray of light incident on a concave mirror is shown by PQ while directions in which the ray would travel after reflection is shown by four rays marked 1, 2, 3 and 4 (Figure). Which of the four rays correctly shows the direction of reflected ray? |
 |
A) 1
B) 2
C) 3
D) 4
Correct Answer: B
Solution :
| Option [b] is correct. |
| Explanation: Incidence ray PQ is coming through principal focus F so it must be parallel to principal axis, that is, either 2 or 4. |
| As it is a concave mirror so, ray cannot go behind the mirror so ray (4) is discarded. |
| So, ray 2 is the reflected ray that verifies answer (B) |
