PPT-Light, lenses, and optics

What is colour A sensation caused by light in our eyes Cones and Rods What is light Particle Wave Rays Weve got our best scientists on it Light is a particle because It has mass and momentum REALLY SMALL. Optics. is the study of the behavior and properties of light.. This includes it’s interactions with objects including mirrors, lenses, and substances which reflect or scatter light..

It denotes patients who have an abnormal sensitivity to light. “Photo-. 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:.
