To solve the problem, we need to determine the frequency of tuning fork B before and after it is loaded with wax, given that it produces 4 beats per second with tuning fork A, which has a frequency of 256 Hz. ### Step-by-Step Solution: 1. **Understanding Beats**: The number of beats per second (N) produced when two tuning forks are sounded together is given by the absolute difference in their frequencies. Thus, we can express this as: \[ N = |f_B - f_A| \] ...
