Answer:
Total time= 2.56 s
Explanation:
Given that
[tex]Distance = 2.4\times 10^5\ miles[/tex]
So distance = 386242560 m
Velocity of light
[tex]C= 3\times 10^8\ m/s[/tex]
We know that
Distance = velocity x time
Now by putting then values
[tex]time=\frac{386242560}{3\times 10^8}[/tex]
t=1.28 s
So the total time = 2 x 1.28
total time= 2.56 s
Explanation:
Given that,
Distance between moon and earth, [tex]d=2.4\times 10^5\ miles[/tex]
1 mile = 1609.34 meters
[tex]d=386241600\ m[/tex]
Speed of light, [tex]c=3\times 10^8\ m/s[/tex]
We need to find the time taken by the light from a source on earth to reach a reflector on the moon and then return to earth. Time is given by :
[tex]t=\dfrac{d}{c}[/tex]
[tex]t=\dfrac{386241600\ m}{3\times 10^8\ m/s}[/tex]
t = 1.28 seconds
Hence, this is the required solution.
