A parallel beam of light is directed at two display panels. A light detector measures the intensity of the reflected light at different angles. The readings are shown in the table.
| Angle of detector from the strongest-reflection direction | Panel A reading (arbitrary units) | Panel B reading (arbitrary units) |
|---|---|---|
| 0° | 90 | 40 |
| 10° | 8 | 35 |
| 20° | 3 | 28 |
Describe the pattern in the data. Identify the type of reflection from each panel, and explain which panel would form the clearer image.
