Question

How can a low pitch have a lot of energy if it has a low frequency and longer wavelength? A. Low-pitched sounds actually have less energy; it's a misconception that they have more energy. B. Low-pitched sounds have more energy because they create stronger vibrations. C. Low-pitched sounds have more energy because they have a higher amplitude. D. Low-pitched sounds have more energy because they travel faster than high-pitched sounds.

Answer 1

Answer: Low-pitch bass notes that humans can barely hear have huge wavelengths of around 17 meters and frequencies around 20 hertz (Hz).

Step-by-step explanation:

Answer 2

The correct answer is C. Low-pitched sounds have more energy because they have a higher amplitude.

In the context of sound waves, the energy of a wave is related to its amplitude, not its frequency or wavelength. A low-pitched sound has a lower frequency and longer wavelength, but it can still have a significant amount of energy if the amplitude (the height of the wave) is large. Higher amplitudes represent greater displacements of air particles, resulting in more energy carried by the sound wave.
