A radar sends a signal to an aircraft at a distance of 30 km away and
receives it back after 2 x 10 -4 second. What is the speed of the signal?
Given t =2 x10
d = 30 km = 30 x 10
Speed of the signal = ?
Let ‘d’ be the distance of aircraft from the radar, then the total distance travelled by the wave in coming and going back = 2 d.
`"Velocity of wave, V"=("Total distance travelled, 2d")/"Time taken, t"`
