Question 1 Report
A photograph of an insect leg is 96 mm long, while the real leg measures 0.8 mm. The magnification of the photograph is:
Answer Details
Both lengths are already in millimetres, so apply the formula directly: \[\text{magnification} = \frac{\text{image size}}{\text{actual size}} = \frac{96}{0.8} = 120.\] The magnification is \(\times 120\) and carries no units. Dividing 96 by 0.8, not by 8, is the key step; misplacing the decimal point gives the wrong values.
