This occurs because "mixing" light is a subtractive process. ]]> 2017-04-20 15:36:27 UTC https://padlet.com/sophie_brignac/hhpcepd7trqv/wish/167299130 Light and how it acts sophie_brignac https://padlet.com/sophie_brignac/hhpcepd7trqv/wish/167300075 Light can be reflected which occurs when the light rays bounce off of the surface they meet.]]> 2017-04-20 15:38:59 UTC https://padlet.com/sophie_brignac/hhpcepd7trqv/wish/167300075 Light and how it acts II sophie_brignac https://padlet.com/sophie_brignac/hhpcepd7trqv/wish/167301043 Light can also be refracted which occurs when the light rays bend as as they cross between 2 different substances (i.e. pencil in water) ]]> 2017-04-20 15:41:39 UTC https://padlet.com/sophie_brignac/hhpcepd7trqv/wish/167301043 EM Spectrum sophie_brignac https://padlet.com/sophie_brignac/hhpcepd7trqv/wish/167302158 The EM Spectrum (electromagnetic) is the range of waves that include radio waves, light waves, and x-rays.
