A radar wave has frquency of `8.1 xx 10^(9) Hz`. The reflected wave from an aeroplane shows a frequency difference of `2.7 xx 10^(3) Hz` on the higher side. Calculate velocity of aeroplane in the line of sight.

A radar wave has a frequency of 7.2xx10^(9) Hz . The reflected wave from an aeroplane shows a frequency difference of 2.4xx10^(3) Hz on the higher side. Calculate the velocity of the aeroplane in the line of sight.

a radar wave has a frequency of 7.8 xx 10^(9) s^(-I) . The reflected wave from an aeroplane shows a frequency shows a frequency difference of 2.7 xx 10^(3) s^(-1) on the higher side. Deduce the velocity of the aeroplane in the line of sight.
