Take a Rubber pipe and stretch it straight and try to see the flame of a candle.
You are able to see the flame through the pipe.

Now bend the same pipe and place one end of the pipe towards the flame and try to see the flame from the other end.

You cannot see the flame as it is blocked.

From this we can say that the light travells in straight paths.
