The wavelength changes inversely with the frequency.
Inductance is inductance, and is not a function of frequency. Frequency affects reactance, and ultimately impedance, not inductance.
Speed affects the frequency and pressure affects the wavelength.
frequency or amplitude
It is less loud. Frequency affects what we hear as pitch. Amplitude affects volume.

The frequency of a wave affects the pitch of sound, with higher frequencies producing higher pitched sounds. The amplitude of a wave affects the loudness of sound, with greater amplitudes producing louder sounds.
It just is. Sound behaves like a wave, and the pitch of the sound affects the wavelength. And wavelength is directly related to the frequency. A high pitched sound has a a shorter wavelength and a higher frequency than a low-pitched sound.
The definition of sound is : "Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations). Therefore sound does not affect frequency but frequency affects the pitch of the sound.
Water affects the travel of radio frequency in terms of attenuation. For example, sea water has high attenuation, causing communication hardly possible.
The frequency of a sound wave affects the pitch of the sound. If the frequency of a wave increases causing more waves for every second, the pitch will go up, and vice-versa.
A wave form consists of a frequency and an amplitude. Sound pitch becomes higher (or more squeaky) with a higher frequency. The volume of sound becomes louder with a higher amplitude.
