relativity

suppose that a line is situated in a X-Y plane that the co ordinate of it's two end is (1,2) and (5,8).i am going just towards X axis in 0.5c.to me what will be the length of the line?

Re: prism

We know that the 7 colors of white light are divided through a prism because in prism they go in different velocity.but there are 4 composite colors in that 7 colors.so why shouldn't they divided

a^2n +b^2n=c^2n

Prove that if $a^{2n}+b^{2n}=c^{2n}$ where $a,b,c$ are positive,then $a^n+b^n>c^n$.Can you do it by geometry?
