light ray การใช้

• The thing is, light rays don't have any foresight or predictive power.
• We need to find in which direction the light ray is reflected.
• Why is a light ray so fast and a whisper so slow?
• However, all these disturbances refract light rays, so they can cast shadows.
• Oblique angle : yup, a light ray bends, see gravitational lens.
• The light rays create a sphere of light surrounding the star.
• The information is filtered from light rays that meet the retina.
• Light rays leave the star in equal amounts in all directions.
• Generally speaking, this means that initially parallel light rays eventually cross or diverge.
• The brightening effect is caused by the bending of light rays by gravity.
• If it clouds or thickens, light rays are unable to pass through it.
• It means that the light ray will emerge parallel to the incident ray.
• While the sphere of light grows, the number of light rays stays the same.
• The light rays are bent, refracted and focused by the cornea, lens, and vitreous.
• We learn more from the light rays hitting our eyeballs than from anything else.
• The sun, for instance, noticeably bends any light rays passing close by its surface.
• The still apparently follows light rays, which seems natural enough.
• Light rays are the boundary between the future, the spacelike, and the past regions.
• In 1704 Isaac Newton suggested that a light ray could be deflected by gravity.
• When the light ray strikes the lens from air, it is not normally incident.
