Can light travel through empty space why is it important? Like all forms of electromagnetic waves, light can travel through empty space, as well as through matter. Light can be absorbed. Absorbed light energy is converted into some other form, such...
What will be observed in an object with relativistic speed moving past an observer at rest? One of the peculiar aspects of Einstein’s theory of special relativity is that the length of objects moving at relativistic speeds undergoes a contraction along...
What is the effect of the term relativistic? (a substantial fraction of the speed of light) The term relativistic effect refers to the difference between what happens according to relativity versus what happens according to models of the physical process that...
What does the general theory of relativity involve that the special theory does not? Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature....
In what frames of reference does special relativity apply? Inertial Frames The cornerstone of the theory of special relativity is the Principle of Relativity: The Laws of Physics are the same in all inertial frames of reference. Which of the following...
What happens to the special theory of relativity if the velocity of light becomes infinite? As an object approaches the speed of light, the object’s mass becomes infinite and so does the energy required to move it. That means it is...
Which is dependent on the observer speed? The amount of contraction of the object is dependent upon the object’s speed relative to the observer. What is special relativity dependent on? Special relatively depends on two postulates: the laws of physics are...
What are the consequences of special relativity? Special relativity had strange and unexpected consequences such as length of objects vary when measured in moving reference frames, mass cannot be accelerated to the speed of light and that time and space are...
Are the laws of motion the same in all frames of reference? The laws of motion are exactly the same in all frames, which is the basis of the Galilean invariance principle—that is to say, the laws of physics do not...
How did Einstein found the speed of light? He didn’t. He just wanted to explore how would a Universe that has a speed limit such as the speed of light would behave… His theory of relativity is the answer to that...
