Document Summary
We are interested at the rate at which light transfers than in the total amount of energy. The rate is called power which we measure in units called watts. White light a mix of all the colors in spectrum. Tv: red, green and blue light -> they are the primary color of vision because they are detected by cells in your eyes. Cmyk process: cyan, magenta, yellow and black are mixed (printer) Scattering: the screen scatters light from the projector in many directions and pages of a book do the same thing. Absorption: placing your hand above a light bulb, your hand absorbs some of the light and this energy warms your hand. Transmission: some forms of matter, glass or air, transmit light which passes through. Reflection/scattering: light can bounce of matter, when the bouncing is the one direction it is a (cid:396)efle(cid:272)tio(cid:374) a(cid:374)d (cid:449)he(cid:374) it"s at (cid:396)a(cid:374)do(cid:373), it is s(cid:272)atte(cid:396)i(cid:374)g.
