Answer:
The Time taken by light to travel from star to the planet is 480 seconds
Step-by-step explanation:
Given as :
The speed of light is [tex]1.8\times 10^{5}[/tex] mile per sec
The distance from star to a planet in its orbit = [tex]8.66\times 10^{7}[/tex] mile
Let the time taken by light to travel from star = T sec
So, Time = [tex]\frac{Distance}{speed}[/tex]
Or, Time = [tex]\frac{8.66\times 10^{7}}{1.8\times 10^{5}}[/tex]
∴, Time = 4.80×10² sec = 480 second
Hence The Time taken by light to travel from star to the planet is 480 seconds Answer
