What Is Relativity? (VCE SSCE Physics): Flashcards

Boundary beyond which no light can escape from a black hole

1922, for photoelectric effect (not relativity)

Dependence of phenomena on relative motion of observer & observed

Non-accelerating frame (stationary or constant velocity)

Theoretical medium scientists thought light travelled through

Null result: beams stayed in phase, disproving aether

Laws of physics same in all inertial reference frames

Speed of light in vacuum constant for all observers

$3.00 \times 10^8 \text{ m} \cdot \text{s}^{-1}$

Relative; different observers measure different time intervals
