In the Michelson-Morley experiment of 1887, the speed at which light traveled through vacuum in perpendicular directions was measured to high accuracy. The data indicated that light traveled at exactly the same speed, independent of which direction it traveled. From this data, scientists concluded that: Select one: a.the speed that light travels through vacuum depends on the speed of the source of light b.light behaves like a stream of particles c.light can eject electrons from a metal surface d.light does not require a medium - it may travel through vacuum

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
