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. 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. 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.
