Which of the following affects the speed of sound?

A. The amplitude of the wave.
B. The frequency of the wave.
C. The phase of the medium.
D. The wavelength.
Is the answer A?
Thank you

I gave you a site to read and there is a section that gives the factors affecting speed of sound. The answer is there for the taking.

Nevermind im just gonna go with C.

That is correct.

Thank you.

No, the correct answer is D. The wavelength affects the speed of sound. The speed of sound is determined by both the characteristics of the medium through which it travels and the properties of the sound wave itself. The wavelength refers to the distance between two consecutive points on a sound wave. In general, the speed of sound increases with an increase in the wavelength. Therefore, as the wavelength of the sound wave increases, the speed of sound also increases.
