7 Michelson-Morley Experiment 4 for test

How did the Michelson-Morley experiment impact the development of physics theories in the 20th century?

• It led to the abandonment of Newtonian mechanics

• It supported the classical theory of electromagnetism

• It paved the way for the theory of relativity

• It had no significant impact on physics theories

What does the term invariant with respect to relativity and the Michelson Morley experiment

• The speed of light is the different for all observers dependent on their relative velocities

• The speed of light is the same for all observers whatever their relative velocities

• The speed of light is can be measured by moving observers

• The faster you move the slower light appears to move
