Final answer:
The beat frequency produced by the superposition of waves with frequencies 300 Hz and 340 Hz is 40 Hz.
Step-by-step explanation:
The frequency of a wave resulting from the superposition of two similar-frequency waves is the average of the frequencies of the original waves.
Therefore, to find the beat frequency produced by the superposition of two waves with frequencies 300 Hz and 340 Hz, we calculate the difference between the frequencies of the two waves.
The beat frequency is given by: 340 Hz - 300 Hz = 40 Hz.
