  2. 2. 2.LIGHT AND SHADOWS  When light cannot travel through an object ,a shadows is formed on the opposite side to the source of light.  COLOURS:  The light we get from the sun is called white light .  White light is a mixture of seven colours: red,orange,yellow,green,blue,indigo and violet.
  3. 3. TRANSPARENT,TRANSLUCENT AND OPAQUE OBJECTS  We divide objects into three groups depending on how much light can pass through .  Transparent objects , like clear glass bottles , allow light to pass through .  Translucent objects, like curtains, allow some light to pass through.  Opaque objects, for example wood and cardboard , do not allow light to pass through .
  4. 4. LUMINOUS AND NON-LUMINOUS BODIES  Some objects are sources of light.  Natural luminous bodies, like the Sun, produce light.  Artificial luminous bodies, like candles and matches , are man-made.  Non luminous bodies produce no light. Some of them can reflect light, like mirrors.
