A radar sends a radio signal of frequency 9×109Hz towards an aircraft approaching the radar. If the reflectedwave shows a frequency shift of 3×103Hz the speed with which the aircraft is approaching the radar in ms–1 (velocity of the radar signal is 3×108 ms–1)

Δvv=2vc∴V=3×103×3×1082×9×109=12×100=50ms−1

Detailed Solution

$\begin{array}{l} \frac{Δv}{v} = \frac{2 v}{c} ∴ V = \frac{3 \times 10^{3} \times 3 \times 10^{8}}{2 \times 9 \times 10^{9}} \\ = \frac{1}{2} \times 100 = 50 {ms}^{- 1} \end{array}$
