Some facts of light

HI in this post I am talking about light.Light is basically what allows us to see around us.There is light around us in our everyday life.Did you know that light travels at the speed of 313 300km/s.Light also travels in a straight line and light reflects.These are some basic facts but what I found most interesting about light is that when light passes through water light is reflected and therefore instead of passing right through, the beam of light will be bent.So if you see a fish there it is actually not at the spot you think it is at but some where away due to the refraction of light .Also the refraction of light is also the very same thing that causes mirages in deserts.
