...approaching conjunction. Roemer suggested that the delay was owing to the greater distance the light had to travel — a distance equal to the diameter of the earth's orbit, or about 190,000,000 of miles. The time was about sixteen minutes. Light was found to travel at the... | |

...The total variation amounts to 16 min. 26.6 sec. This must therefore be the time which light takes to travel a distance equal to the diameter of the earth's orbit, or about 184,000,000 miles ; its velocity is therefore very nearly 186,500 miles per second. This value... | |

...186,000 miles per second and sound travels about 1190 feet per second. How long would it take light to travel a distance equal to the diameter of the earth's orbit? How long would it take sound to travel the same distance ? 19. The difference in potential between... | |

...times of eclipses with the earth successively at A and at B, we can infer the time taken for light to travel a distance equal to the diameter of the earth's orbit. This was Roemer's discovery, in fact. But if this time is measured when Jupiter is first at A', and... | |
