PPT-Colors reflected and absorbed

Remember the color of an object that you see is the color it is reflecting the object absorbs all other colors A lime Colors Reflected Colors Absorbed Red orange yellow green blue indigo violet. internal emitter iodine radium strontium tritium cesium absorbed dose rate kg MeV MeV brPage 4br Health effects depend on how radiation interacts w th bio ogical material at the microscopic level Radiation delivers energy in small pa ckets not unifo Different colors correspond to different wavelengths of visible light. 665 nm. 630 nm. 600 nm. 550 nm. 470 nm. 425 nm. 400 nm. Today’s Lab. If we shine light on an object, some light is absorbed and some is reflected. 5.6C . Demonstrate . that . light. travels in a straight line until it strikes an object or travels through one medium to another and demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces and refracted such as the appearance of an object when observed through water.. Color. NGSS. MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials. . Objectives. Content Objectives:. Participate in a gallery walk to discuss properties of light and its behavior. . What is it and how does it work. a. type of electromagnetic radiation of a specific wavelength. Some of these wavelengths we can see (visible light) . Some wavelengths we cannot see (x-rays, infrared, ultraviolet). Light. Light Energy. Light Energy. Energy is the ability to cause things to change. Light is a type of energy. Without light no one can see anything. Light gives things color. Light shines on plants and makes them grow. Some doctors use light energy to perform operations with lasers. Light energy can make cars move. Satellites turn light into electricity in space.. What is color. ?. Color – different colors – . are the ways our eyes. perceive different wavelengths. o. f LIGHT. r. eflected from objects. The reflected waves are the ones we perceive as color.. Multiple scattering in cloud or aerosol layers. τ. =0. τ. =. τ. *. Fraction absorbed fraction transmitted fraction reflected = 1. REFLECTED. ABSORBED. TRANSMITTED. Direct & diffuse transmission. Demonstrate . that . light. travels in a straight line until it strikes an object or travels through one medium to another and demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces and refracted such as the appearance of an object when observed through water.. Art 3 & 4. C. o. l. o. r. and V. a. l. u. e. Each are only visible because of . light.. Light and Darkness . are used in legends of most cultures. Ted . Video. C. o. l. o. r. and V. a. l. u. e. element of design. 3 dimensions. hue. value. chroma. Hue-. the descriptive name of color . (i.e. red, yellow, & green). pure color w/o black, white, or gray added. defines a specific spot on the color wheel . Basic Properties. Light travels in straight “beams”. beams = the length, height, and width of light. Basic Properties. Light travels much faster than sound. Speed of light = 983,571,056 feet per second!. Nanotech. Vanderbilt Student Volunteers for Science. What is nanotechnology?. A nanometer is a billionth of a meter. . That’s . really, really . tiny. ! . Nanoscale. science. focuses on things that are measured in nanometers, including atoms and molecules, the basic building blocks of our world. . When light encounters a different medium it can either be reflected, absorbed, or pass through. Most of the time it is some level of each.. A blue shirt reflects blue light (and a few others) absorbs all other colors of light and allows small intensities of all colors (white light) to pass through. .
