Reading Light Through Turned Sheets
Base your answers on the information provided and your knowledge of chemistry. Use the 2025 Chemistry Reference Tables as needed.
A display sends 100 light units through sheets that select a direction of light vibration. The first sheet passes 50 units and sets their vibration direction. Each later sheet acts on the light reaching it. It passes all light aligned with its own direction, none at 90°, and half at 45°. Any light it passes leaves aligned with that sheet.
| Trial | First sheet | Last sheet |
|---|---|---|
| P | Horizontal | Horizontal |
| Q | Horizontal | Vertical |
