Light is a form of electromagnetic energy that makes things visible. Light travels extremely fast and over long distances, carries energy and information, travels in straight lines, bends and bounces when it comes in contact with objects, has color, and has different intensities, and can be bright or dim. To measure light waves we use nanometers which equivalent to one billionth of a meter. ]]> 2017-02-28 22:03:40 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156881327 alfredomc1236 https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156884428 Incandescence is a process that makes light heat. Fluorescence is the process that makes light directly from electricity]]> 2017-02-28 22:24:46 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156884428 alfredomc1236 https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156884933 Color is how we perceive the energy of light. The color we see is the color that is being reflected, which is the one that is not actually in it. White light is the combination of all colors together. Red light has the lowest energy we can see, and violet has the highest energy we can see. Photons are the smallest possible amount of light, in the form of a wave bundle.]]> 2017-02-28 22:29:16 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156884933 alfredomc1236 https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156886425 The speed of light is 300,000,000 m/s which is about 1,000,000 times more than the speed of light. ]]> 2017-02-28 22:39:38 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156886425 alfredomc1236 https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156887073 An electromagnetic wave is a traveling oscillation in the electric and magnetic field.

The electromagnetic spectrum consists of radio waves, microwaves, infrared lights, visible light, ultraviolet light, x-rays, and gamma rays.

We have 3 cone cells for color. One for low energy light, like red ones. One for medium energy light, like green ones. The third one is for high energy light, like blue ones. ]]> 2017-02-28 23:03:47 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156889385 alfredomc1236 https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156890913 This is what are used to show color on a TV or other screen.

Reflection occurs when light bounces off a surface. Specular reflection is a surface reflection, where each incident ray produces only one reflected ray. Diffuse reflection is a surface reflection, where each incident ray produces many scattered rays. Refraction occurs when light bends while crossing a surface or moving through a material. Index of refraction is a number that measures how much a material is able to bend light.]]> 2017-02-28 23:47:52 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/156893839 alfredomc1236 https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/157115499 2017-03-01 17:59:16 UTC https://padlet.com/alfredomc1236/ip36v3nfyfte/wish/157115499
