approaching the light, the Doppler effect caused a blue shift that made the light appear green λ=5000 A. How fast would you have had to be moving for that to be true? Would the judge be justified in giving you a speeding ticket? Explain your way out of going to jail.

When a liquid is spung within a cylindrical vessel,the level of the liquid does not remain horizontal, but it rises up along sides of the walls of the cylinder. For spinning we give only a horizontal angular force to the liquid. But how can the liquid rise up like that without any vertical force applied or generated?.
