Document Summary
3-1 newton discovered that white is not a fundamental colour and. Refraction: change of direction as light travels from one medium to another. Spectrum: result of spreading colours (sunlight through a prism spreads the light into the colours of the rainbow) mixture of colours. Colours of a full spectrum are properties of the light and white light is a. Individual colours from refracted light are unchanged by a second prism o. Two light waves meet with one going up and one going down they would interfere and partially or totally cancel each other out leaving dark regions. Two waves meetings that are both going up or both going down, they o. Electric and magnetic effects travel through space together in the form of reinforce each other and create bright regions couples waves that have equal amplitudes visible light. Some of these waves (electromagnetic radiation) are observed as o. Different colours of light are waves with different wavelengths.
