To solve the problem of how many beats are produced between the direct and the reflected sound from a tuning fork approaching a wall, we can follow these steps: ### Step 1: Identify the Given Values - Frequency of the tuning fork (f) = 512 Hz - Velocity of the tuning fork (v_s) = 4 m/s (approaching the wall) - Velocity of sound in air (v) = 332 m/s ### Step 2: Calculate the Apparent Frequency of the Direct Sound ...
