A jet fighter flies in a straight line over an airfield line over and airfield with a speed 264 m/s level with the ground, at a height of 600 m. If it emits a continuous note of frequency 1 kHz, what is the change in apparent frequency (in Hz) as experienced by one of the ground crew over a 1.5 s interval as the jet flies overhead? (Assume speed of sound is\[340m{{s}^{-1}}\])
