| 1. | The thing is, light rays don't have any foresight or predictive power.
|
| 2. | We need to find in which direction the light ray is reflected.
|
| 3. | Why is a light ray so fast and a whisper so slow?
|
| 4. | However, all these disturbances refract light rays, so they can cast shadows.
|
| 5. | Oblique angle : yup, a light ray bends, see gravitational lens.
|
| 6. | The light rays create a sphere of light surrounding the star.
|
| 7. | The information is filtered from light rays that meet the retina.
|
| 8. | Light rays leave the star in equal amounts in all directions.
|
| 9. | Generally speaking, this means that initially parallel light rays eventually cross or diverge.
|
| 10. | The brightening effect is caused by the bending of light rays by gravity.
