Question 1

Describe a method the student could have used to obtain the data in Table 1. You may include a labelled diagram.

Table 1 shows the results:
Angle of incidence (degrees): 10, 20, 30, 40, 50, 60
Angle of refraction (degrees): 6, 12, 18, 23, 28, 32

Accepted Answer

This question requires a step-by-step description of a standard physics practical. Structure your answer logically.
- **Equipment:** What do you need? (e.g., glass block, paper, ray box, protractor, ruler).
- **Setup:** How do you set it up? (e.g., draw around the block).
- **Procedure:** What do you do? (e.g., shine a ray, mark its path).
- **Measurements:** What do you measure and how? (e.g., use a protractor to measure angles relative to the normal).
- **Control/Repetition:** How do you get a range of results? (e.g., change the angle of incidence).

Question 2

What mistakes do candidates make on this AQA GCSE question?

Accepted Answer

✗ Forgetting to draw the normal and measuring angles from the surface of the block instead.
✗ Not being specific about what equipment to use (e.g., saying "a light" instead of "a ray box").
✗ Describing a reflection experiment instead of a refraction experiment.
