Describe a method the student could have used to obtain the results in Table 5 - AQA - GCSE Physics - Question 9 - 2022 - Paper 1

The student should place a glass block on a flat surface. Using a ray box, they should shine a ray of light through the glass block at various angles of incidence.

1. Setup:

   • Ensure the glass block is on a stable surface.
   • Position the ray box at one end of the block, aiming towards the block.

2. Measurement:

   • For each angle of incidence, use a protractor to measure the angle at which the ray enters the block.
   • Mark the angle based on the normal line drawn at 90 degrees to the surface of the block.

3. Recording Data:

   • Measure the angle of refraction as the ray exits the block using the protractor again.
   • Record both angles in a table, specifying the angle of incidence and the corresponding angle of refraction.

4. Repeat:

   • Repeat this process for angles of incidence from 10 degrees to 80 degrees, ensuring measurements are taken at regular intervals (e.g., every 10 degrees).

5. Labelled Diagram:

   • A labelled diagram could show the ray box, the glass block, the normal line, the incident ray, and the refracted ray.
