UNEB A level physics optics revision notes.
Light is a form of energy that travels in a straight line.
Some objects produce light on their own and these are called luminous objects e.g sun, fire worms, fire
fly .
Most objects we see don’t produce light on their own but reflect it from luminous objects and these are
called non-luminous objects e.g. moon, the stars, etc.
