Is a form of energy that has a particle and wave nature Light Is a form of energy that has a particle and wave nature

Light travels in straight lines Its travel is represented by a ray A ray is a straight line a with an arrow showing the direction of travel A ray A group of rays represent a beam of light A beam

There are three main types of beams of light: Parallel beams Convergent beams Divergent beams Use your dictionary to write down the meanings of Parallel ______________________________ Convergent ___________________________ Divergent ____________________________

A torch light creates a divergent beam, attempt to draw a beam of light from the torch light to show a divergent beam using the diagram below. Example: Is it? or or Headlights on a car creates parallel beams, attempt to draw a beam of light to show a parallel beam using the diagram below A magnifying glass creates convergent beams, attempt to draw a beam of light to show a convergent beam using the diagram below

Luminous versus non-luminous If you are given the definition that luminous objects produce it own light and non-luminous objects reflect light, make a list of at least five objects that are luminous and non-luminous objects Luminous objects Non luminous objects
