Question

1. compare the sounds produced by wave a and wave b. the human ear would hear - wave a has a louder sound than wave b because of its higher amplitude. wave b has a louder sound than wave a because of its higher amplitude. wave a has a louder sound than wave b because of its lower frequency. wave b has a louder sound than wave a because of its lower frequency.

Explanation:

Amplitude of a sound wave relates to loudness (higher amplitude = louder). From the graphs, Wave B has a greater amplitude (taller peaks/ deeper troughs) than Wave A. Frequency relates to pitch, not loudness, so options about frequency are incorrect. Thus, Wave B is louder due to higher amplitude.

Answer:

B. Wave B has a louder sound than Wave A because of its higher amplitude.
