## The Attempt at a Solution

[/B]

Normall I would put my working up but I have been looking at this question for well over an hour and can't really make a start, I originally through that looking at Maxwell equation for a light wave would help but that just showed me the equations above. I then throught well ##n=\frac{c}{v}=\frac{c_0}{c}=\sqrt{\mu _r\epsilon _r}## but this gave me 1.1 so that was a no go, at that all I have, I just done know how to start this type of question off can some give a nudge in the right direction please. I am quite new to all this so, is it possible not to go too deep straight away, thanks in advance.
