Question:What properties does the material have that can reflect light?
Answers received: Strip must be shiny, light-coloured or smooth to be able to reflect a lot of light.
Light waves shine out from a light source, bounce off objects and into your eyes.
Reflector, a device that causes reflection (for example, a mirror or a retroreflector).Something which reflects heat, light or sound, especially something having a reflecting surface is called a reflecter.
ReplyDeleteSurfaces that are shiny, with a different proportion of diffuse or specular reflection.
ReplyDelete1.Those surfaces which reflect the most light appear white, or silver. A highly polished, smooth and flat silver surface acts as a mirror, reflecting a perfect image of the world around it.2.Reflection occurs when waves encounter a boundary that does not absorb the radiation's energy and bounces the waves off the surface. The incoming light wave is referred to as an incident wave and the wave that is bounced from the surface is called the reflected wave.
ReplyDeleteWhat happens when light falls on an object?
ReplyDeleteWhen light falls on an object,it can be:
Reflected(bounce off)
Refracted(bend)
Absorbed
Pass through an object.
There are two types of reflections,they are:
Regular and Irregular reflections.
As the surface atoms absorb wave energy, they become unstable, and regain stability by releasing portion of the absorbed light from their electron orbits. Due to reflection of light occurring in a precisely consistent, predictable manner, reflective surfaces can be manipulated to re-direct or re-shape optical wavefront into spherical, needed for the purpose of imaging.
ReplyDeleteLight-coloured and shiny objects reflect light better than dark and non-shiny objects.The Moon is not a light source. The light we see coming from the Moon is reflected light from the Sun.
