A fax message is to be sent from Delhi to washington via a geostationary satellite. Calculate the minimum time delay between
the dispatch and its getting received. Take
height of the geostationary satellite = 36000
km.

Text Solution

Verified by Experts

Distance to be travelled by fax message
`S = 2h = 2 xx 36000 km = 72000 km`.
Time delay `= S/c = (72000 xx 1000 m)/(3 xx 10^8 m//s) = 0.245s` .
