What examiners said
Many candidates gave the answer as 4.8 and did not include the 10–7 from the label on the graph as part of their answer.
— Examiner report, October/November 2023, 0973/41 Q12(b)(i) (Cambridge)
There were two common errors made in the responses to this question. Firstly, some candidates did not convert centimetres to metres, giving a value of 1.6. Secondly, misreading the wavelength. A value of 0.032 cm was commonly seen.
