Which graph BEST represents the relationship between the potential energy and kinetic energy of a cannon ball as it flies over t
he bow of a ship and then falls onto the beach on the other side? Note that the dotted line represents potential energy while the solid
line represents kinetic energy
So n=c/v, n= index, c=speed of light and v= speed of light in diamond. 2.42=c/v so v=c/2.42, c≈<span>3x108 m/sec</span><span> so v=</span><span>1.24x108 m/sec</span>. <span>Hope this helps.</span>
