    Microwaves are reflected from a distant airplane approaching a stationary observer. It is found that when the reflected waves beat against the waves radiating from the source, the beat frequency is 900 Hz. Calculate the approach speed of the airplane if the wavelength of the microwave is 0.1 H. Velocity of microwave is 3 xx 10^(8)" m/s".

    An indian submarine is moving in the Arabian sea with constant velocity. To detect enemy it sends out sonar waves which travel with velocity 1050(m)/(s) in water. Initially the waves are getting reflected from a fixed island and the reflected waves are coming back to submarine. The frequency of reflected waves are detected by the submarine and found to be 10% greater than the sent waves. Now an enemy ship comes in front, due to which the frequency of reflected waves detected by submarine becomes 21% greater than the sent waves. Q. The velocity of enemy ship should be
