Visible light is the only kind of electromagnetic wave that we can see and most light rays are just imaginary lines that represent the motion of visible light waves. However, there are still problems with this definition. Things that are alive do certain things, like move and grow and sometimes change. Here, the index of refraction of medium 1 and 2 are a1 and a2, respectively. While there are many light rays, three types are most common; incident rays, reflected rays, and refracted rays. Light rays are imaginary lines that represent the motion of waves of visible light. /Length 7 0 R The greater percentage of carbon dioxide emission gas is caused human activities including deforestation, mining, transportation, industries, land use, the burning of fuels, just to name a few. Most of this light reflects off the ozone layer but the rays that penetrate can cause sunburn on unprotected skin. If the object or surface is shiny, like glass, the light will reflect at the same angle as it hit the surface, creating specular reflection. Students explore concepts in astrobiology through calculations. The magnification power of a Dissecting microscope ranges from 5x-80x. Answer (1 of 10): The green plants would all die. By either putting light through a slit, or using a laser beam, we can create something resembling a light ray and show the effects of reflection and refraction. You are alive, so is a bug, a fish, and your teacher. ratio of sin 1 and sin 2 (sin 1 / sin 2 ) = ratio of refractive index (n1 / n2), The index of Refraction of medium 1 and 2 are n1 and n2, respectively. (2009, December 17). Parallel: When rays from a distant point source travel parallel to each other in a particular direction, it forms a parallel light beam. 12 Which statement is correct about the laws of reflection: (i) The incident ray, normal ray and the reflected ray all lie in the same plane.
