Light behaves in a very predictable manner. Light can only travel in a straight line (most of the time…). The . Law of Reflection. states that the INCIDENT (incoming) light’s angle will be exactly the same as the reflecting light’s angle. Light travels in a STRAIGHT LINE . ANOTHER WAY TO THINK OF LIGHT. Light leaving the candle travels in all directions, but we only SEE the light that travels in to our Eye-Brain. ANOTHER WAY TO THINK OF .

"Since, in practice, we normally cannot solve the full electron-nuclear problem,. they are: Geometrical optics - this area of optics operates on the primary assumption that light travels in a straight line. Although this is an abstraction of reality, it nevertheless permits rathe Optics of Vision . Optics of Vision . Refraction power a lens “Diopter” = 1 m / focal length. Optics of Vision .

Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable.. Raytracing. Lecture 7: Optics. UCSD Physics 122. 2. Reflection. We describe the path of light as straight-line rays. “geometrical optics” approach. Reflection off a flat surface follows a simple rule:. Geometric Optics.
