What examiners said
Most candidates answered correctly, although a small minority of candidates measured the angle between the incident ray and the mirror, leading to an incorrect answer of 35°.
— Examiner report, October/November 2023, 0653/61 Q3(a) (Cambridge)
The instruction was that P1 and P2 should be marked with a cross and that they needed to be at least 5 cm apart. Most did this correctly, though some candidates wrote P1 and P2 near the line but did not clearly indicate the position of the pins with crosses.
— Examiner report, October/November 2023, 0653/61 Q3(b)(i) (Cambridge)
Candidates found this demanding. Many lines were drawn that did not start at Y. Those that started in the correct place often did not meet the pupil of the eye and did not go through the cross at P3. The strongest responses showed a line from Y that went through point P3 and hence hit near the centre of the pupil. P4 could then be indicated on this line.
