Postulates of relativity - Study guides, Class notes & Summaries

PHYS 1260 Exam 4 with correctly explained test. Superposition and Interference - correct answers.- same wave + same wave = reinforcement - two opposite waves = cancellation - two similar waves = partial cancellation - interference patterns of overlapping waves from 2 vibrating sources - interference pattern = caused by interference b/w a pair of waves - constructive interference produces bright region where waves reinforce each other (waves arriving in phase) - destructiv...

Postulates of Relativity

Special Relativity is a theory in physics that describes the relationship between space and time, and how they are affected by the motion of objects. It is based on two postulates: the laws of physics are the same for all observers in uniform motion, and the speed of light is constant for all observers.

Why was the hypothesis of Luminiferous Aether introduced? - The Hypothesis of Luminiferous Aether was introduced to answer the question; "when light moves through a vacuum what is it that oscillates"? Since it was known that when acoustic waves move through a medium the wave is really the propagating disturbance of the medium whose particles ossicles as the wave moves. Therefore since physicists could not conceive of light waves propagating without a physical medium to do so, it was ...
