A radar sends a radio signal of frequency $$9$$ x $$109$$ Hz towards an aircraft approaching the radar. If the reflected wave shows a frequency shift of $$3$$ x $$103$$ Hz, the speed with which the aircraft is approaching the radar, in $$m/s$$ is $$(velocity$$ of the radio signal is $$3$$ x $$108$$ $$m/s$$

Question

Infinity Learn · Accepted Answer

Let vs, be the velocity of jet, then change in frequency dn is given $$bydn=n2vsc$$  or  $$3$$×$$103=9$$×$$109$$×$$2vs3$$×$$108$$ $$vs=3$$×$$103$$×$$3$$×$$1082$$×$$9$$×$$109=50m/s$$

A radar sends a radio signal of frequency 9 x 10⁹ Hz towards an aircraft approaching the radar. If the reflected wave shows a frequency shift of 3 x 10³ Hz, the speed with which the aircraft is approaching the radar, in m/s is (velocity of the radio signal is 3 x 10⁸ m/s
