Because when light enters a new substance, its speed changes. In order for the law demonstrated in the equation (frequency = speed/wavelength) to remain the same, the wavelength of the light particle/wave must shorten or lengthen. This change causes the wave to slightly refract to one side or the other.
If something refracts light it bends it.
It refracts light
No, a mirror can not refrect. Instead, it can reflect. Water is an example of a substance that refracts.
Yes.

When white light passes through a triangular prism, it refracts, meaning, the light bends. When white light refracts, it disperses (separates) into the colours it is made up of - ie. the colours of the rainbow.
