LIGHT THEORY In light theory there are 4 things the first thing is light particles the second thing refraction the third thing is reflection the last thing spectrum of colour the light has light waves the white light 7 colours which are RED,ORANGE,YELLOW,GREEN,BLUE,INDIGO AND VIOLET. the light works light particles or light wave.
light particles the light particles are called photons which is what light made up of photons are atoms that make the light which give the light particles is the small parts of light that make light beam.b the practicals can move in any directions you want you can re factions it or reflect it or also you can change the colour of the light particles by using an transparent object which is colourful.
refraction refraction change the direction of the light wave. the white light beam hits the prism and it changes the directions of the light wave it creates an optical illusion you think the object is under you but it far away from you then you think.
reflection the reflections is the light particles hit a object that shines the light particles will bounce of the object and it will reflect it shows the opposite picture of your image like mirror shows you that called reflections.
