If two photons are travelling at right angles to each other with velocity vectors of c then what is the velocity vector of the hypotenuse of the right triangle and does this velocity triangle form an equilateral triangle with three angles of 90 degrees if c^2 + c^2 = c^2(adsbygoogle = window.adsbygoogle || []).push({});
