Rules for obtaining images formed by convex lens. In convex lens, the image is always formed at a point where at least two refracted light rays meet.. Rule 1: A ray of light which is originally ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond ...

Refraction is the bending of light rays. Normally, light travels in a straight line, and changes direction and speed when it passes from one transparent medium to another, such as from air into glass.
