Answer:
It will take 0.093 seconds to our voice to reach or to be heard at the other end.
Explanation:
The total distance covered by the wave = 28000 km = 28,000,000 m
1 km = 1000 m
Speed of the light = [tex]3\times 10^8 m/s[/tex]
Time taken by the electromagnetic wave to travel the given distance = T
[tex]Speed=\frac{Distance}{Time}[/tex]
[tex]T=\frac{28,000,000 m}{3\times 10^8 m/s}=0.093 s[/tex]
The time taken by the electromagnetic wave is 0.093 seconds.
