How to use in-sentence of “speed of light”:
+ Energy is “e”, force is “f”, mass is “m”, acceleration is “a” and speed of light is sometimes “c”.
+ The reason for measuring time in units of the speed of light times the time coordinate is so that the units for time are the same as the units for space.
+ According to special relativity, a particle cannot move faster than the speed of light in a vacuum.
+ One Planck time is the time it would take a photon travelling at the speed of light to cross a distance equal to one Planck length.
+ Time is relative and the speed of light through a vacuum is the only constant.
+ The speed of light is constant, so we will apply this value to two problems.
+ This is done in digital circuits by multiplying the speed of light by the time it takes to receive the radar energy reflected back from an object.
+ However, this implies that the size of the observable universe and the particle horizon is continually getting smaller — the distance at which objects are moving away at the speed of light from an observer becomes ever closer, and the distance over which interactions can propagate becomes ever shorter.
Example sentences of “speed of light”:
+ That is light, or other signals, All electromagnetic radiation, and also gravitational waves, all of which are limited to the speed of light in a vacuum.
+ Any clock used to measure a duration will be wrong by exactly the right amount so that the speed of light remains the same.
+ That is light, or other signals, All electromagnetic radiation, and also gravitational waves, all of which are limited to the speed of light in a vacuum.
+ Any clock used to measure a duration will be wrong by exactly the right amount so that the speed of light remains the same.
+ What made Einstein’s theory so revolutionary is that it considers the measurement of the speed of light to be constant by definition, in other words it is a law of nature.
+ It has an apparent motion of four times the speed of light relative to the galaxy centre.
+ This example shows that knowing the frequency of an electromagnetic wave gives you the wavelength, since all electromagnetic waves travel at the speed of light so that c = v where v is frequency and lambda is wavelength, and c is the speed of light.
+ The index of refraction of a clear material is the ratio between the speed of light in a vacuum and the speed of light in that material.
+ The interferometer was designed to measure the speed and direction of the “aether wind” by measuring the difference between the speed of light traveling in different directions.
+ Since the speed of light is such a big number, this means that even a small amount of matter can have a lot of energy.
+ According to him, the measured speed of light should be different for different speeds of the observer in comparison with its source.
+ The special theory of relativity is based on the prediction, so far upheld by observations, that the measured speed of light in a vacuum is the same whether or not the source of the light and the person doing the measuring are moving relative to each other.
+ If the particle moves faster than the speed of light in that medium, the emitted waves add up and at an angle with respect to the particle direction a radiation is emitted which is known as Cherenkov radiation.
+ Basically, the world lines show that when the speed of light is reached, time stops for the observer.
+ This equation means is that before adding the amount of mass to the amount of energy, the mass must be multiplicationmultiplied by the speed of light and then by the speed of light again.
+ The finite speed of light is a major constraint on long-distance space travel.
+ Theoretical ParticleTheoretical particles which go above the speed of light are called tachyons.
+ Blazars are AGN with a relativistic jet relativistic = moving at or close to the speed of light which is pointing in the general direction of the Earth.
