Light - Coggle Diagram

- - - - Translucent: objects that let light pass through them partially are translucent objects
      - Opaque: Objects that do not let light pass through them are called opaque objects.
      - Transparent: Objects that let light pass through them are transparent objects
- - - - The shape of the shadow may not identical as it depends on where the light source is placed and where the shadow falls
      - The size and intensity of the shadow depends on the size of the light source and the distance between the light source and the object.
      - A small light source will give a sharp shadow
        
        A larger light source will give a dark central shadow and a lighter shadow surrounding it.
- - - - The refraction light as it passes from one transparent substance or medium to another is due to the change in the speed of light
        
        If the light slows down when it moves from one medium to another the ray bends towards normal.
        
        If the light speeds up as it passes from one medium to the next. the ray bends away from normal
- - - - The white light from the sun contains light of different wavelengths which give different coloured light.
        
        When they pass through the prism the light waves of different wavelengths travel at slightly different speeds and are spread out, by a process called dispersion, to form colours of a spectrum
        
        The light waves with shortest wavelengths are slowed down and refracted the most.
