Chapter 35 – Flashcards

Relativity equations for time, length and momentum hold true for

How fast would a light beam appear to Einstein if he were traveling in the same direction at 90% of the speed of light?

Event A occurs before event B in a certain frame of reference. In another frame of reference, event A could occur

All events and all things exist in "the spacetime continuum" with coordinates

Clocks on a spaceship moving at high speed relative to the Earth run more slowly when viewed from

Compared to clocks in a stationary reference frame, clocks in a moving reference frame run

When a moving spaceship emits regularly-spaced flashes of light, how frequently you see the flashes depends on the ship

As you approach a steady light source, the wavelength of the emitted light appears

Harry takes a space voyage and returns to find his twin sister has aged more than he has. This is evidence that

As a spaceship moving toward you at half the speed of light fires a probe toward you, relative to itself at 0.7 the speed of light, you see the probe approaching at about

To outside observers at rest, the overall sizes of objects traveling at relativistic speeds are

Objects moving at relativistic speeds appear to observers at rest to be

Electrons fired in vintage TV tubes traveled at about 0.25 times the speed of light, having more momentum and energy than would be required classically to get that speed. Strictly speaking, this

What does c2 have in common with γ?
