Question

In the 2015 film Star Wars: The Force Awakens, there is a scene in which Rey and Finn are in the Millennium Falcon, trying to outrun some tie fighters. The tie fighters make some pretty tight aerial maneuvers, sometimes flying straight at or straight away from the camera. The camera can be taken as stationary. Through some audio analysis, when the tie fighters were flying directly at the screen, the observed frequency was 726.3 ??. The speed of sound on this planet can be assumed to be the same as on earth (340 ?⁄?), and the idling engine tone frequency is 680.0 ??.

1. What is the speed of the tie fighters as they fly toward the screen?

2. At a later point, the Millennium Falcon (which flies at the same speed as the tie fighters) turns around and flies directly at the tie fighters. What is the frequency of the sound

   emitted by the tie fighters, as heard by an observer on the Millennium Falcon?

Answer 1

Doppler effect is used to find the observed frequency relation for stationary observer and approching source in the first case and moving source and observer when boty are approching each other.
