For eg. we r watching the live telecast of any event in the world on tv so how much time wud the signal from satellite take, from & back to the earth. If there is any special formula plz tell me.

The signals are transmitted at the speed of light ..
186,000 miles per second.
Let us imagine a satellite at 10,000 miles from earth in synchronous orbit. (always in the same place relative to a point on earth.
The signal is travelling out & back = 20,000 miles.
20,000 ÷ 186,000 = 0.1075 seconds.
A formula of sorts would be: - (Distance of satellite x 2) ÷ 186,000
= seconds for transmission out and return.

These signals are transmitted on an electro-magnetic wave, a microwave signal. It is therefore transmitted at the speed of light.

Formula: add the Distances from source of signal (Broadcaster) to sattelite then add the distance to your reciever, then (Divide) use light speed ~186,000 mps (miles per second) or 300,000,000 mps (Meters Per second)

The easiest way is to make one another count, say or do something to a rhythm, like a hip-hop call and response. You can immediately tell how off the feed is.

DirecTv is in geosynchronous orbit, 42164km, so round trip time is about 0.28 seconds:
