Description: ∙Communicating with the Voyager Spacecraft The Voyager 1 spacecraft has traveled farther than any other man-made object, and in August 2012 it entered into interstellar space when it was a distance of 1.8 ×10^13 m from Earth. How many hours elapsed between the time a command was sent from Earth and the time the command was received by Voyager when it entered interstellar space?

Key Concepts

Signal Propagation Delay

Signal propagation delay refers to the time lapse required for a signal, such as a command transmitted to a spacecraft, to travel from the sender to the receiver. This concept is crucial for understanding communication with distant objects, as the delay is directly proportional to the distance the signal travels.

Unit Conversion and Time Calculation

Accurate calculations in physics often involve converting measurements between different units. When determining communication delays, it is important to convert the time calculated in one unit, such as seconds, into another preferred unit, such as hours, to ensure clear and meaningful interpretation of the results.

Speed of Light

In physics, the speed of light in a vacuum is a constant that represents how fast electromagnetic waves propagate. This constant is essential for calculating how long signals take to travel across space since it dictates the fundamental limit on the speed of information transfer.
