Ray optics

Ray optics. Every point on a luminous or illuminated surface produces light rays in all available directions. The image in a plane mirror is called a virtual image , meaning that no light rays pass through the image. Rather light rays only appear to originate at the image.

Refraction of Light

Refraction of Light. Chapter 15.1. Reflection vs. Refraction. Reflection is the turning back of light. All objects reflect some or all of its light. Refraction is the bending of light. Transparent objects bend light when passing through them (refraction). Refraction.

Mirages

Mirages. - Refractive index decreases in the warmer air (where the density is lower) . - (b) Incoming light ray gets progressively bent towards the horizontal. - (c) Lower portion of horizontal ray moves slightly faster than upper portion since it is still in the warmer air.
