REFLECTION OF LIGHT<\/h2>\n

Light is a form of energy that causes the sensation of vision. There are natural and artificial sources of light.<\/p>\n

    \n
  1. Natural Sources:<\/strong> Sun, stars etc\u2026<\/li>\n
  2. Artificial Sources:<\/strong> Bulbs, fluorescent tubes, candles, lamps, torches, arc light etc\u2026<\/li>\n<\/ol>\n

    LUMINOUS\u00a0OBJECTS:<\/strong> These are objects that generate and emit light by themselves. Examples are the sun, stars, fireflies, some deep-sea fishes etc\u2026<\/p>\n

    NON LUMINOUS OBJECTS:<\/strong> These are objects that depend on luminous objects to illuminate them. We cannot see them until they reflect light from luminous objects. Examples are The moon, road signs, bricks, our bodies, books, clothes etc\u2026<\/p>\n

    RAYS AND BEAMS<\/h3>\n

    A ray is a direction that lights energy travels. Rays are not real but imaginary lines. A beam is a collection of rays.<\/p>\n

    TYPES OF BEAMS<\/h3>\n

    PARALLEL BEAM: This is a beam in which the rays are parallel to each other. Searchlights give off parallel beam.

    DIVERGENT BEAM: This is a beam in which the rays spread from the source. Examples are the sun, lamps, and bulbs produce divergent beams.\"reflection\"<\/span><\/p>\n

    CONVERGENT BEAM: This is one in which the rays meet at a point. A hand lens produces a convergent beam.<\/p>\n

    PRINCIPLE OF REVERSIBILITY OF LIGHT<\/h3>\n

    It states that the path of light is reversible and rectilinear propagation of light is the phenomenon of light traveling in a straight line.<\/p>\n

    REFLECTION OF LIGHT AT PLAIN SURFACES<\/h3>\n

    Reflection is the bouncing off of light from a surface. When light falls on a surface, three things happen to it;<\/p>\n
