Exam 35: Special Theory of Relativity

If the frequency of blinks for a light source appears to double as the light source approaches you, the frequency of blinks as it moves away from you at the same speed

The Lorentz factor, γ,

The speed of light is

According to the special theory of relativity, all laws of nature are the same

The ether theory of light propagation is

A light source blinks once per second in its own frame of reference. As you approach the blinking source, you observe the frequency of blinks to be

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

A spaceship traveling very fast relative to you fires a stream of photons at speed c away from you. You measure the photons' speed to be

An astronaut traveling forward at 0.87c holds a meterstick in spear-like fashion. An observer at rest sees the spear's length as

When we apply the Lorentz factor γ to length contraction, we

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

A certain light source blinks once per second in its own frame of reference. As you recede from the blinking source, you observe the frequency of blinks to be

When an object of mass m is pushed to relativistic speed v, its momentum is

There is an upper limit on the speed of a particle, which means there is also an upper limit on its

Relativity equations for time, length and momentum hold true for

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

According to special relativity, tomorrow's travelers can travel

You and a friend can share the same space and time measurements when

An astronaut traveling forward at 0.87c holds a meterstick in spear-like fashion. This astronaut sees the spear's length as

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