A woman drops a vibrating tuning fork, which is vibrating at 516 Hertz, from a tall building. Through what distance (in m) has the tuning fork fallen when the frequency detected at the starting point is 484 Hertz? (Assume the speed of sound in air is 343 m/s.)

Answer #1

Concept used:- here as the source (the fork) moves away from the observer, its speed increases and hence the apparent frequency decreases, so we first use the Doppler effect in sound to find the speed and then use kinematics to find the height fallen,

    A bicyclist is moving toward a sheer wall while holding a tuning fork rated at 464 Hz. If the bicyclist detects a beat frequency of 6 Hz (between the waves coming directly from the tuning fork and the echo waves coming from the sheer wall), calculate the speed of the bicycle. Assume the speed of sound is 343 m/s.
