Question

An opera singer who is a baritone, lowers his pitch and raises his voice for a song. Which best describes how the resulting sound wave has changed? The sound wave will have:

a lower amplitude and higher wavelength

a lower amplitude and higher frequency.

a higher amplitude and lower frequency.

a higher amplitude and faster speed

Answer 1

Answer: 3.

Step-by-step explanation:

The correct answer is a higher amplitude and lower frequency. Since an opera singer is lowering his pitch it means that he is creating higher amplitude and because he is raising his voice for a song with that higher amplitude he is creating lower frequency.
