Aug 19, 2011 · Properties of light. Light travels in straight lines and very fast, faster than sound. We see objects because they reflect light into our eyes, while shadows are formed when light is blocked. There are two main types of reflection - specular reflection off smooth surfaces like mirrors, and diffuse reflection off rough surfaces.
Aug 27, 2013 · Statefields School, Inc. This document discusses key properties of light including reflection, refraction, diffraction, and interference. Reflection occurs when light bounces off a surface, following the law that the angle of incidence equals the angle of reflection. Refraction is the bending of light when passing from one medium to another at ...
Jan 23, 2014 · 10 properties of light. The document discusses several key properties of light, including: - Reflection - Light bounces off surfaces at the same angle it hits. - Refraction - Light bends as it passes from one medium to another, changing speed. The degree of bending depends on the medium's index of refraction.
Aug 7, 2012 · 9) The human eye :-9) The human eye :-The human eye is the sense organ which helps us to see objects around us. The eye ball is almost spherical in shape. Light enters the eye through a transparent membrane called cornea. Behind the cornea is a muscular structure called iris which has an opening called pupil.
Download ppt "Properties of Light." Light as a Wave Light (or electromagnetic radiation), can be thought of as either a particle or a wave. As a wave, light has a wavelength, (distance between waves) a frequency, (number of waves passing you each second) a speed, c = (this is always the same: 300,000 km/s) an energy, E = h (where h is just a ...
