Answer :
Final answer:
Light takes 8 minutes and 19 seconds to travel from the Sun to Earth, impacting our real-time perception of the Sun's state. Understanding this time span involves calculations based on the speed of light and the distance to the Sun. The concept of light-minutes provides a clear and precise measurement of the Sun's distance from Earth.
Explanation:
Light takes approximately 8 minutes and 19 seconds to travel from the Sun to Earth due to the vast distance between the two celestial bodies. This duration is crucial in understanding that we perceive the Sun's light as it was over 8 minutes ago.
Calculations involving the speed of light (2.998x10^8 m/s) and the distance from the Sun to Earth (1.496x10^11 m) confirm this time span, illustrating the constant speed of light and its impact on our perception of astronomical events.
By using light-minutes as a unit of measurement, the Sun is described as 8 light-minutes away from Earth, emphasizing the convenient and precise nature of this measurement in astronomical contexts.
