Light travels in a straight line through an homogenous
medium. It can be proved by an experiment given below.
Arrange two pieces of cardboard, having pin holes at the
centre of each, vertically, one behind the other. They
should be arranged in such a way that the two holes are
exactly in the same level with each other. Now place a
candle behind and in level with the hole of the second
cardboard. It will be visible when viewed through the hole
of the first cardboard. Now displace one of the cardboards
slightly to its life or right candle would no longer be
visible. This shows that light travels in a straight line.
