What happens to the Lorentz factor at non-relativistic speeds? Galilean relativity true Special relativity false General relativity false Preferred frame false Single Which of the following situations involve an inertial reference frame? A pea moving within a centrifuge false A pendulum swinging back and forth false A truck stuck in traffic true A rock undergoing free fall false Single What does the first postulate of Einstein's special theory of relativity state? All laws of physics apply in all frames of reference true Laws of physics apply for all inertial frames of reference false There is an absolute frame of reference to compare motion false Light has a fixed speed regardless of frame of reference false Single According to the second postulate of Einstein's special theory of relativity, what is unique about light? It follows the laws of physics in all reference frames false It follows the laws of physics in inertial reference frames only false It has a fixed speed in a vacuum regardless of frame of reference true Its speed is 3.0 x 10₈ m/s regardless of its medium of propagation false Single In contrast with Einstein's theory of special relativity, his theory of general relativity differs in that: Effects of the index of refraction are accounted for in the speed of light false Effects of gravity and non-uniform motion are also considered true The frame of light is considered the absolute frame of reference false Light can accelerate or decelerate depending on frame of reference false Single Because time flows at different rates for different observers, it follows that two events witnessed by the same two observers: May or may not have occurred false May or may not be simultaneous true May or may not be the same events false May or may not have the same frame false Single Before Hertz verified the electromagnetic wave nature of light, scientists thought that light travelled within an invisible medium called the: plenum false corpuscular space false vacuum of space false luminiferous aether true Single A paper in which topic earned Einstein his sole Nobel Prize in Physics? Proof of the Bose-Einstein condensate false General theory of relativity false Special theory of relativity false photoelectric effect true Single What year did Einstein first publish his paper concerning Special Theory of Relativity? 1902 false 1903 false 1904 false 1905 true Single The time interval between two events as measured by an observer at a rest frame is called? proper time true relaxation time false time dilation false relativistic time false Single
