AI Generated Solution

To solve the problem, we need to determine the frequency of the sound wave reflected from the wall that the bat will hear. We will use the Doppler effect formula for sound. ### Step 1: Understand the scenario The bat is flying towards a wall, emitting sound at a frequency of 450 kHz. The speed of the bat (source) is 6 m/s, and the speed of sound in air (c) is 340 m/s. ### Step 2: Calculate the frequency of the sound wave as it reaches the wall Using the Doppler effect formula for a source moving towards a stationary observer (the wall), the formula for the observed frequency (f') is given by: ...
