Question

If you make an intercontinental phone call, your voice is transformed into electromagnetic waves routed via satellite in geosynchronous orbit at an altitude of 28 000 km. About how long does it take before your voice is heard at the other end?

Answer 1

It will take 0.093 seconds to our voice to reach or to be heard at the other end.

Step-by-step explanation:

The total distance covered by the wave = 28000 km = 28,000,000 m

1 km = 1000 m

Speed of the light =
`3* 10^8 m/s`

Time taken by the electromagnetic wave to travel the given distance = T

`Speed=(Distance)/(Time)`

`T=(28,000,000 m)/(3* 10^8 m/s)=0.093 s`

The time taken by the electromagnetic wave is 0.093 seconds.
