SCIENCE

• Light is a form of energy it is the reason why we have solar panels
• Light travels in a straight line
• Light travels away from the light source
• Light loses energy the further away it moves away from it source
• Light is released and spreads in all directions
• Reflection - allows objects to be seen that do not produce their own light

  e.g. mirror
• Refraction - when light is refracted it passes from one type of transparent material to another and changes direction
• Light can actually slow down
• Absorption - it does not pass through or reflect from a material instead it remains in the material as another form of energy
• Heat - vibration of molecules/stunned energy in molecules
• Transmission - how light travels
• Transparent - allows the light to pass through
• Translucent - partially transparent ( limited ways )
• Opaque - does not allow light to pass through
• Photon - particle of light
• Cctv uses convex mirrors
• Real - projectors
• Virtual image - what you see in a mirror
• Angle of incidents and

  Angle of reflection are both equal
• Vacuum - the fastest way a light can travel
