Question
The first part shows a man producing a sound with a wavelength of 2.0 m and a frequency of 165 hertz. The speed calculated using the formula, wave speed = frequency times wavelength, is 330 meters per second = 165 hertz times 2.0 m. The second part shows a woman producing a sound with a wavelength of 0.2 m and a frequency of 1650 hertz. The speed calculated using the formula, wave speed = frequency times wavelength, is 330 meters per second = 1650 hertz times 0.2 m.
Which statement regarding sound traveling in air is correct?

Responses
The frequency of a sound does not affect the speed at which it travels.
The frequency of a sound does not affect the speed at which it travels.
As the wavelength increases, the frequency also increases.
As the wavelength increases, the frequency also increases.
A wave with a shorter wavelength is always faster than one with a longer wavelength.
